Here's the requested and useful info - full commands and outputs below
in case the quick info misses anything.
The setup is a bit convoluted sorry, it's a cheap initial attempt at a
script to build multiple versions of gcc and llvm. I'm using GIT
instead of SVN now, but the issue is the same.
QUICK INFO
================
build CWD: "/make/tool/gcc/build/gcc-unk-2020-05-08-06-10-20"
build configuration:
"/make/tool/gcc/git/gcc-unk-2020-05-08-06-10-20/configure
--disable-bootstrap --disable-multilib --enable-languages=c++
--prefix=/make/tool/gcc/use/unk-2020-05-08-06-10-20
--program-suffix=-unk"
-v (full output below) has one line showing the issue:
"COLLECT_LTO_WRAPPER=/home/xaxazak/Fast/make/tool/gcc/use/unk-2020-05-08-06-10-20
bin/../libexec/gcc/x86_64-pc-linux-gnu/11.0.0/lto-wrapper"
NOTE: "/make" is the symlink for to "/home/xaxazak/Fast/make" that I
don't want expanded
output of "g++-unk -E -x c++ - -v < /dev/null" contains many lines
using expanded path, eg:
"
#include <...> search starts here:
/home/xaxazak/Fast/make/tool/gcc/use/unk-2020-05-08-06-10-20/bin/../lib/gcc/x86_64-pc-linux-gnu/11.0.0/../../../../include/c++/11.0.0
"
================
I note that the output from make ends with lines like:
"make[4]: Leaving directory
'/home/xaxazak/Fast/make/tool/gcc/build/gcc-unk-2020-05-08-06-10-20/x86_64-pc-linux-gnu/libatomic"
So perhaps the issue is that the symlinks are being expanded within make?
