Hi all.
I am trying to use GSL in my C project on GuixSD.
address@hidden ~/cproj$ guix package --search-paths
export PATH="/home/brettg/.guix-profile/bin"
export GIT_EXEC_PATH="/home/brettg/.guix-profile/libexec/git-core"
export XDG_DATA_DIRS="/home/brettg/.guix-profile/share"
export GIO_EXTRA_MODULES="/home/brettg/.guix-profile/lib/gio/modules"
export CPATH="/home/brettg/.guix-profile/include"
export LIBRARY_PATH="/home/brettg/.guix-profile/lib"
export INFOPATH="/home/brettg/.guix-profile/share/info"
export
PYTHONPATH="/home/brettg/.guix-profile/lib/python3.7/site-packages"
According to the GCC documentation, the compiler should automatically
use the CPATH to search for GSL, but it does not seem to respect this.
test.c:2:10: fatal error: gsl_blash.h: No such file or directory
#include
^~~~~~~~~~~~~
compilation terminated.
I am not using an isolated environment or anything, so the CPATH
variable is set, and I can return it. It also is correctly listed in cpp
-v
address@hidden ~/cproj$ cpp -v
Using built-in specs.

Alright. That is all! Thanks in advance.
