[package] libiconv/1.17: fails to build with `clang` on Windows #25245

Open mmomtchev opened 2 weeks ago

mmomtchev commented 2 weeks ago

Description

libiconv fails to build with clangon Windows - this is a different problem from the other iconv problems:

https://github.com/conan-io/conan-center-index/issues/20848 https://github.com/conan-io/conan-center-index/issues/20477

This is a more recent problem that seems to be common throughout the autotools-based recipes when using clang.

That class of problems is caused by a GNU make that cannot read cygwin-style paths (/c/users...), using the GNU make from MSYS2 fixes the problem - maybe these recipes should pull the dependency

mmomtchev commented 1 week ago

The problem is that make/4.4.1 from conan has the same problem while the make.exe from msys2/cci.latest does support this style of paths, however it does not work with CMake.
