[lfs-support] GCC-$.8.1 Configure fatal errors
Greetings, back in GCC-4.8.1 again section 5.5.1 - after re-reading everything I decided to do as suggested to try to find out why I am having so much difficulty with this 'make'. In the config.log I found the following fatal errors: Thread model: posix gcc version 4.7.2 (Debian 4.7.2-5) configure:4212: $? = 0 configure:4201: gcc -V 5 gcc: error: unrecognized command line option '-V' gcc: fatal error: no input files compilation terminated. configure:4212: $? = 4 configure:4201: gcc -qversion 5 gcc: error: unrecognized command line option '-qversion' gcc: fatal error: no input files compilation terminated. It is also failing while checking for versions .10 and .11 of ISL: conftest.c:10:25: fatal error: isl/version.h: No such file or directory. After the the configure appears to complete successfully. Should I be concerned about either of these two failures?

Thanks, William No, it is testing a system for which compiler is installed and which options to include for the build. If configure fails, then it is a problem. If configure exits in success, then it is fine. You will see lots of failed tests in the config.log. It doesn't mean the configure script failed.

Should I be concerned about either of these two failures? Hello William, The configure script tries a lot of things to guess the capabilities of the system. Sometimes, an error contains some informations that are usefull to determine those capabilities. For example, to test if a header file (say xxx.h) can be accessed, it runs gcc on a small C program, which contains a line: #include xxx.h Then, if gcc ends with an error, configure interprets it as xxx.h being not acessible, and may stop or not, depending whether xxx.h is required or not. Meanwhile, you'll see the error message of gcc, somthing like: cannot find xxx.h or whatever. It does not mean that configure found an error. So the outpur you see is not configure errors, but negative tests. You do not have to be worried about that. So, go ahead, and run make.

I had learned by experience rudiments of you what you wrote, but this is a very good explanation and hpoe to get it organized in my mind. :-) -- []s, Fernando -- http://linuxfromscratch.org/mailman/listinfo/lfs-support FAQ: http://www.linuxfromscratch.org/lfs/faq.html Unsubscribe: See the above information page
