...I got the "validation test" working by setting C_INCLUDE_PATH:
cat > hello.c <<EOF
#include <stdio.h>
int main()
{
printf("Hello, world!\n");
return 0;
}
EOF
echo $CPATH
# /home/maxd/GNU/opt/gnu/gcc-12.1.0/include:/usr/include
export C_INCLUDE_PATH=$CPATH
$INSTALL/bin/musl-gcc hello.c
./a.out
# Hello, world!
For what it's worth:
[/home/maxd] 56> cat /proc/version
Linux version 4.19.0 (mockbuild@...lder1.eng.sw.ru) (gcc version 4.8.5 20150623 (Red Hat 4.8.5-44) (GCC) ) #1 SMP Thu Dec 15 20:31:06 MSK 2022
[/home/maxd] 57>
However, my application built with this musl-gcc still ends with
Killed
albeit after running for about the expected time.
Are there other environment variables I should be concerned about?
