Hi Mathieu,
I'm using the attached patch to build guile-lzlib for the 64bit Hurd.
When configure tries to detect the shared library name, the Hurd's gcc-14 says
--8<---------------cut here---------------start------------->8---
x86_64-pc-gnu-gcc conftest.c -o conftest -llz -Wl,--verbose
foo.c: In function ‘main’:
foo.c:1:22: error: implicit declaration of function ‘LZ_decompress_open’ [-Wimplicit-function-declaration]
1 | int main () { return LZ_decompress_open(); }
| ^~~~~~~~~~~~~~~~~~
--8<---------------cut here---------------end--------------->8---
The solution could be to compile using -Wno-implicit-function-declaration,
or to just declare the function, which is what this patch does.
Greetings,
Janneke
