HOW TO COMPILE AND INSTALL TIGCC FROM SOURCE ============================================ Please note: read README.linux first. The instructions below apply only to compiling and installing the whole package from source if you need to do that. I recommend installing from binaries if possible. REQUIREMENTS ------------ You must have the following programs before you attempt to install tigcc-unix. REQUIRED: 1. gcc 2.95 or later (other compilers are NOT supported) 2. binutils 2.8 or later (gnu or equivalent -- ld, ar, as, etc.) 3. gnu patch (Solaris patch will NOT work) 4. bzip2 (to decompress this archive) 5. tar (gnu tar is best, but Solaris and SGI should be okay) 6. gnu make 7. At least 130 MB of free space (archive expands to over 80, build can take another 30-40 depending upon architecture) 8. bison or yacc 9. flex OPTIONAL: 10. Windows or (not tested) WINE to compile the documentation from source (optional: the source distribution includes pre-generated HTML documentation) 11. A dialog executable (any of: kdialog, xdialog, gdialog, cdialog or dialog), if and only if you want to use the wizard (optional: the wizard now uses plain bash if no dialog executable is available) If you run into any problems, please contact me and let me know where the install failed... If you want to recompile TIGCC-Linux, you will need to dowload: gcc-core-4.0.2.tar.bz2 (gcc-core, full gcc may not compile !) binutils-2.16.1.tar.bz2 Depending on your machine, compilation can take some time ! INSTALLING TIGCC FOR UNIX ------------------------- The installation should be very simple. The package has worked on Linux, Solaris 8, and SGI IRIX 6 to try and make the scripts compatible. UN*X provides some things better, some things worse. Let we know if you have a problem with the worse... First, extract the source to a directory of your choosing such as /tmp. Unpack binutils & gcc-core packages to the download/ directory as this, and create symlinks download/gcc.ti and download/binutils.ti pointing to them. Note that the sources on tigcc.ticalc.org ONLY support Linux/x86 and Windows, so you will need the COMPLETE GCC (gcc-core only, not the whole compiler collection) and Binutils sources from a GNU mirror for all other platforms. So, you should have done it like this: mkdir /tmp/tigcc-src cd /tmp/tigcc-src # substitute the directory you are using for /tmp bunzip2 tigcc-src.tar.bz2 tar xfv tigcc-src.tar mkdir download cd download bunzip2 binutils-2.16.1.tar.bz2 gcc-core-4.0.2.tar.bz2 tar xvf binutils-2.16.1.tar tar xvf gcc-core-4.0.2.tar ln -s binutils-2.16.1 binutils.ti ln -s gcc-4.0.2 gcc.ti cd .. At this point, you have 2 options: 1. Use the installation wizard ------------------------------ All you need to do now is: cd scripts; ./Install and follow the instructions. If you want a text-mode install on a system with KDE installed, you can use: cd scripts; DIALOG=dialog ./Install to tell the script to use the text-mode (curses) dialog instead of kdialog. You will be prompted for: * the destination directory you want to install TIGCC to ($TIGCC) * the bootstrap compiler ($CC) you want to compile TIGCC with (usually "gcc") * the optimization flags ($CFLAGS) you want to compile TIGCC with (read the GCC documentation or just use the defaults) The wizard will ask you whether you want to apply the TIGCC patch. The answer is usually "Yes". It will be "No" only if you are rebuilding the same source for a second (or more) time. When done, the wizard will ask you whether you want to add your $TIGCC setting to bashrc. If you answer "Yes", you are done here, you only need to restart bash. If you prefer to do things by hand, answer "No" and follow the instructions in section 2.1 below. (If you selected "No", but changed your mind, you can also run envreg by hand afterwards.) 2. Use the install scripts directly ----------------------------------- 2.1. Environment variable settings ---------------------------------- Now, set the environment variable TIGCC to the directory you want to install TIGCC into (for example /usr/local/tigcc). You need to set this variable in your profile, because the compilation stage needs it to find some tools and tigcc front-end needs it to find the header files. If you use bash, add it to your .bashrc file in your home directory. You could also use your .profile or .login if you have those. If you use tcsh or csh, put it in your .cshrc file (or if you use .tcshrc, put it there). I've never used korn shell. You're on your own if you do. For bash/sh users export TIGCC=/usr/local/tigcc export PATH=$PATH:$TIGCC/bin For csh/tcsh users setenv TIGCC /usr/local/tigcc set path=($path $TIGCC/bin) I've had problems using setenv to reset the path in tcsh. setenv path "$path ${TIGCC}/bin" doesn't seem to work. You may need to logout and log back in for that to take effect. Or you can resource your profile. source ~/.profile source ~/.bashrc source ~/.cshrc source ~/.tcshrc You only need to resource the file you changed. 2.2. Installation ----------------- The hard part should be over. Now, just change into the directory you extracted tigcc into cd /tmp/tigcc-src Optionally, you can now rebuild the HTML documentation from source: the required source code is in tigcclib/doc/source.tar.bz2 in your source tree. See the last section below for instructions to compile the documentation. Note that the tools to compile the documentation from source are for Windows only, so you will need Windows (or maybe WINE; I have not tested whether it works for those tools though) if you want to build the documentation from source. Unless of course you manage to port the Delphi sources of those tools yourself. Note that it comes precompiled, so you need not do this. (As for platform- independence: the documentation is "compiled" into platform-independent HTML files, so compiling it from source should usually not be necessary.) And run the installation script... export CFLAGS='-Os -s' cd scripts; ./Install_All Assuming you have all the required tools, you should have yourself a tigcc build in 5 - 60 minutes. I don't know how much time it will take you. It took less than 10 minutes on a Linux system with a Pentium II 450 and 128 MB RAM. But, it took 45 minutes on a Linux system with a K6 233 and 112MB RAM. It took nearly 40 minutes on a Solaris Sparc 400 with 256 MB RAM, but it had to read off a network with many other users, so that may have had some impact on compile time. It took over an hour on an SGI O2 machine. I would assume it's due to the slow SGI c compiler, which binutils and gcc will try and compile themselves with. Since you have a recent version of gcc, try setting CC=gcc and CXX=g++ to speed things up. You must have gcc 2.95 or above for this to work. I hope this installation goes smoothly for you. 2.3. ALTERNATE WAY for installation ----------------------------------- The following is the "hard" way to do step 2.2. It is used primarily for development purposes. You can use this if you experience some problems with the automated script. At first, you will have to register a variable depending on the location you want to install TIGCC export TIGCC=/usr/local/tigcc export PATH=$PATH:$TIGCC/bin export CFLAGS='-Os -s' Next, simply go into the scripts directory. Then you must apply the patch supplied with this package: ./Install_step_1 Next, compile binutils and gcc. This may take a while... ./Install_step_2 If everything went correctly, you now should have a working Tigcc for Linux compiler. For installing the TIGCC library, simply launch: ./Install_step_3 If you want to be able to use it, you should add /usr/local/tigcc to your PATH. The compiler is named m68k-coff-gcc, to avoid namecollision with your system's gcc. The other utilities follow the same naming. You may need the TIGCC Tools Suite utilities (required for using the tigcc front-end). Simply do: ./Install_step_4 At last, you have to install the full documentation by ./Install_step_5 REBUILDING THE DOCUMENTATION FROM ITS TRUE SOURCE (REQUIRES WINDOWS) -------------------------------------------------------------------- This section is lifted from Sebastian's Readme.txt accompanying the Windows source release. Note that the Linux/Unix source release includes pre-generated HTML documentation, so you only need to rebuild it if you modify the hs? files. First, modify the file HelpSystem.ini in the 'Programs' subfolder of the 'Doc' folder to reflect your actual folder names. It exists so that the 'Programs' folder can reside at any given place on the hard disk. Then, you need to call all 'Update...' programs once. UpdateInclude.exe and UpdateInfo.exe take one or more complete file name(s) as parameters. The actual names of the files are discarded, and the remaining folder name is the folder to be updated. If the first parameter is '/ALL' or no parameters are specified, all folders are updated, and in case of UpdateInclude.exe, a header file index is generated. UpdateKeywords.exe and UpdateIndex.exe do not take any parameters. To compile the documentation, download the HTML Help Workshop from http://msdn.microsoft.com. Then compile the project in the 'System\CHMFiles' folder. Tools to make editing help system files more convenient are also included in this distribution. A tools to create help system files from the original GNU Texinfo documents is included as well, but it might need a recompilation to work with future versions of the documentation. Anyway, the .texi files should be in the current directory, and you should specify one of them in the command line. The appropriate subfolders need to exist (e.g. gnuexts). If you need detailed information about the file formats, look at the Readme.txt file in the documentation folder. When done with building the CHM documentation, you can convert it to the QT assistant format using my converters: cd srcdir/doc/converter # substitute the directory you are using for srcdir gcc -Os -s -Wall -W -Wwrite-strings chm2dcf.c -o chm2dcf # compile chm2dcf cd ../html ../converter/chm2dcf # convert the CHM to a Documentation Content File (DCF) ../converter/dcf2adp # convert the DCF to an Assistant Document Profile (ADP) (There is also a script called updatedoc to automate the copying and converting of the documentation.) WARNING: chm2dcf is slooooow. You have been warned.
