Hey list,
My configure.ac updates CXXFLAGS periodically during execution, such as
via pkg-config. Some of the include paths returned from pkg-config's
--cflags contain spaces which I require. It's paths are properly
escaped, so this is not a problem thus far.
$ pkg-config --cflags libfoo
-I/some/path\ space
The problem is then when CXXFLAGS is amended with what is returned
breaking further conftests. This is fine:
CXXFLAGS="$CXXFLAGS -I/some/path/no_spaces"
This breaks:
CXXFLAGS="$CXXFLAGS -I/some/path\ space"
All succeeding conftests appear to bail. The config.log is revealing:
...
configure:9444: g++ -c -g3 -std=c++11 ... -I/some/path\ spaces conftest.cpp >&5
g++: error: spaces: No such file or directory
...
If I run what appears to be what configure executed (g++ ...), it
executes fine. However, by the looks of it, the argument vector was
broken up unintentionally.
I'm assuming I am not doing something correctly. Any help appreciated.
Respectfully,
