Hi Nelson,

I cannot reproduce the problem.  With =E2=80=98guix environment=E2=80=99, a=
s show below,
I build an isolated environment that contains nothing but
=E2=80=98gcc-toolchain=E2=80=99 and Bash:

--8<---------------cut here---------------start------------->8---
$ guix environment --ad-hoc -C gcc-toolchain
[env]$ echo 'int main() { }' > t.c
[env]$ gcc t.c
[env]$ ./a.out
--8<---------------cut here---------------end--------------->8---

As you can see, I can compile and link in that environment.

This environment defines PATH, CPATH, and LIBRARY_PATH appropriately:

--8<---------------cut here---------------start------------->8---
$ guix environment --ad-hoc -C gcc-toolchain grep coreutils
[env]$ env | grep PATH
CPATH=3D/gnu/store/26ng85mn5rs22cw654bvh62wh0yjx89h-profile/include
LIBRARY_PATH=3D/gnu/store/26ng85mn5rs22cw654bvh62wh0yjx89h-profile/lib
PATH=3D/gnu/store/26ng85mn5rs22cw654bvh62wh0yjx89h-profile/bin:/gnu/store/2=
6ng85mn5rs22cw654bvh62wh0yjx89h-profile/sbin
--8<---------------cut here---------------end--------------->8---

Can you check the value of CPATH and LIBRARY_PATH in your user shell?

What does =E2=80=98guix package --search-paths=E2=80=99 return?

(See also the bits about search paths and ~/.guix-profile/etc/profile at
<https://gnu.org/software/guix/manual/en/html_node/Invoking-guix-package.ht=
ml>.)

HTH,
