int, void **)’ [-Wincompatible-pointer-types]
writing for better clarity, we can see that, 'pointer to function' conversion
is attempted.
FROM
void (*)(char *, char *, char *, int, char **, int, void *, int, void **)
TO
void (*)(void)
This pathology is seen in C code.
WORKAROUND
A workaround is to weaken the type enforcement, as seen below
export CFLAGS="-Wno-error=incompatible-pointer-types"
or for a specific command
CFLAGS="-Wno-error=incompatible-pointer-types" ./configure
TAFSEER
With the release of GCC-15, given strict type checking, a lot of 'legacy' C
code will give compilation errors.
