Subject: Include paths for cpp/g++ (gcc 4.3.0)
Date: Mon, 05 May 2008 08:11:00 -0000 [thread overview]
Message-ID: <76a336670805050111l282a8663s8a929556f46d5ca1@mail.gmail.com> (raw)
Hello,
123456789012345678901234567890123456789012345678901234567890123456
I have problem building cpp with my installation of gcc 4.3.0, which I
built from
source. The specific problem in this case is that it can't find the system
wctype.h, but I don't know if it applies to other system header files.
This is using GoboLinux, so paths may differ from "normal" systems, but files
should be available where expected.
Header files is found in /System/Links/Headers (as symbolic links) and
wctype.h (the file g++ can't find) is located there:
$ls -l /System/Links/Headers/wctype.h
lrwxrwxrwx 1 gobo gobo 44 May 5 03:35 /System/Links/Headers/wctype.h ->
../../../Programs/Glibc/2.8/include/wctype.h
$ls -l /Programs/Glibc/2.8/include/wctype.h
-rw-r--r-- 1 1000 100 11208 May 3 13:02 /Programs/Glibc/2.8/include/wctype.h
CPLUS_INCLUDE_PATH is set to /System/Links/Headers.
Also /usr/include is a symlink to /System/Links/Headers, so if any binary uses
that as absolute path it should find the files. This is applied to /include and
/usr/local/include as well. Though this shouldn't matter as g++ searches
/System/Links/Headers, as can be seen below. To workaround reading
symlinks I also tried the below compilation with
'-I/Programs/Glibc/2.8/include',
which had no more effect than adding it to the top of <...> include search
paths, but still I got the same error.
What is wrong with my install?
$cat something.cpp
#include <cwctype>
$g++ -v -c something.cpp
