Hi,
If I guix shell to arm-none-eabi-toolchain:
```
Ekaitz@tuxedo ~/projects/TESTS$ guix shell arm-none-eabi-toolchain
```
arm-none-eabi-toolchain can't use cstdlib because:
```
Ekaitz@tuxedo ~/projects/TESTS [env]$ cat a.c
#include <cstdlib>
void operator delete(void *p) { std::free(p); }
Ekaitz@tuxedo ~/projects/TESTS [env]$ arm-none-eabi-g++ a.c
In file included from a.c:1:0:
/gnu/store/6bq6svar4b2mkp2k3laxqqs1nsxykrvf-profile/arm-none-eabi/include/c++/cstdlib:75:15: fatal error: stdlib.h: No such file or directory
#include_next <stdlib.h>
^~~~~~~~~~
compilation terminated.
Ekaitz@tuxedo ~/projects/TESTS [env]$
```
But:
```
Ekaitz@tuxedo ~/projects/TESTS [env]$ ls $CROSS_C_INCLUDE_PATH | grep stdlib
stdlib.h
```
Ideas?

Hi,
I dug a little bit further and I found a very interesting behavior:
Preprocessor doesn't work vanilla:
```
Ekaitz@tuxedo ~/projects/rp2040/TESTS/RANDOM [env]$ arm-none-eabi-cpp a.c
# 1 "a.c"
# 1 "<built-in>"
# 1 "<command-line>"
# 1 "a.c"
a.c:1:10: fatal error: cstdlib: No such file or directory
#include <cstdlib>
^~~~~~~~~
compilation terminated.
```
We have CROSS_CPLUS_INCLUDE_PATH correctly set:
```
Ekaitz@tuxedo ~/projects/rp2040/TESTS/RANDOM [env]$ echo $CROSS_CPLUS_INCLUDE_PATH
/gnu/store/6zcm3xq6d3a0j6pnjd09b3zj1c9qbmrl-profile/arm-none-eabi/include:/gnu/store/6zcm3xq6d3a0j6pnjd09b3zj1c9qbmrl-profile/arm-none-eabi/include/c++:/gnu/store/6zcm3xq6d3a0j6pnjd09b3zj1c9qbmrl-profile/arm-none-eabi/include/c++/arm-none-eabi
```
If we insert exactly the same directories pointed by CROSS_CPLUS_INCLUDE_PATH manually to the preprocessor it works!
```
Ekaitz@tuxedo ~/projects/rp2040/TESTS/RANDOM [env]$ arm-none-eabi-cpp a.c -I/gnu/store/6zcm3xq6d3a0j6pnjd09b3zj1c9qbmrl-profile/arm-none-eabi/include -I/gnu/store/6zcm3xq6d3a0j6pnjd09b3zj1c9qbmrl-profile/arm-none-eabi/include/c++ -I/gnu/store/6zcm3xq6d3a0j6pnjd09b3zj1c9qbmrl-profile/arm-none-eabi/include/c++/arm-none-eabi

...
```
Anyone has an idea of what I'm missing here and why isn't it just automagic?
It should just work, or am I superwrong?
Thanks!

Oh! Too fast!
It was a different problem!

```
The problem is with C++ only.
With C, as per the previous email, I managed to pass the preprocessing step, but in C++ it doesn't!
It doesn't really matter if I play with the -I flag.
It just doesn't work :(

Hi Ekaitz!
I tried to reproduce your problem, and indeed it produces the same error
you are encountering.
$ guix shell arm-none-eabi-toolchain
[env]$ ls
a.c
[env]$ cat a.c
#include <cstdlib>
void operator delete(void* p) {std::free(p);}
int main() {return 0;}
[env]$ arm-none-eabi-g++ -x c++ a.c
In file included from a.c:1:0:
/gnu/store/6bq6svar4b2mkp2k3laxqqs1nsxykrvf-profile/arm-none-eabi/include/c++/cstdlib:75:15:
fatal error: stdlib.h: No such file or directory
#include_next <stdlib.h>
^~~~~~~~~~
compilation terminated.
Then I tried it with my self build toolchain
gcc12-cross-newlib-arm-none-eabi-toolchain-12.2.0¹, which works as expected:
$ arm-none-eabi-g++ -x c++ -c a.c
$ ls
a.c a.o
$ arm-none-eabi-g++ -x c++ a.c -lg -lrdpmon
$ ls
a.c a.o a.out
$ file a.out
a.out: ELF 32-bit LSB executable, ARM, EABI5 version 1 (SYSV),
statically linked, with debug_info, not stripped
Bye
Stefan
