I have established that the Redhat 8, SUSE 9.2 and Debian Woody ports install OK. I've been told that Slackware 10 can also be installed manually (see my other post for more details on all of the above). The next step is to get a working set of gcc tools. Unfortunately, the linux_devtools port is broken and so is the gentoo port which I believe would bootstrap itself and then install everything (including gcc tools, I assume) from source. Gentoo was also my preference because portage would seem to be the most port-like way of system maintenance. With the above working Linux environments I seem to have the following options for installing the gcc toolset. 1) binary RPMs 2) tarballs 3) apt-get/dpkg/dselect Although the first two are a bit of a fiddle to carry out that is not a real problem. I have done (1) for the SUSE port, but when I use gcc I get this: cc: installation problem, cannot exec `cc1': No such file or directory make: *** [LD_search.o] Error 1 Checking cc -v gives: Using built-in specs. Configured with: ../configure --enable-threads=posix --prefix=/usr --with-local-prefix=/usr/local --infodir=/usr/share/info --mandir=/usr/share/man --enable-languages=c,c++,f77,objc,java,ada --disable-checking --libdir=/usr/lib --enable-libgcj --with-gxx-include-dir=/usr/include/g++ --with-slibdir=/lib --with-system-zlib --enable-shared --enable-__cxa_atexit i586-suse-linux Thread model: posix gcc version 3.3.4 (pre 3.3.5 20040809) So I guess it is looking in all the wrong places for it's libraries. I have tried to alleviate that in the makefile C flags with: CC = /compat/linux/usr/bin/cc -B/usr/compat/linux/usr -B/usr/compat/linux/usr/local -B/usr/compat/linux/lib -B/usr/compat/linux/usr/lib -I/usr/compat/linux/usr/include/g++ But it doesn't change anything. I haven't tried (2) because I couldn't successfully install slackware yet. I'm not clear whether the problem of hard-coded directories mentioned above would be alleviated or not. Maybe someone has already produced a tarball or RPM which contains the gcc tools set up correctly for /compat/linux/? I like (3) - which is probably the default method in Debian - because it is automatic and would handle dependencies, but I am worried that the automatic tools could install stuff all over my / directory rather than inside /compat/linux/ where I want it all to stay. Also not sure whether they would/should store their databases inside /compat/linux or on /. Any thoughts or tips that lead to a safe and effective solution for this much appreciated and a great help to the software development community on FreeBSD who want to target Linux. If I can get it working and learn enough about port makefiles then I could try to automate it and make it available.
