Open Blackhex opened 10 months ago

Blackhex commented 10 months ago

This issue serves for tracking progress and documenting issues needed to be overcome while adding aarch64-w64-mingw32 target to mingw-w64-cross-binutils package.

This is a subtask of https://github.com/msys2/MSYS2-packages/issues/3834, for broader discussions, please, head there.

The development is happening in this branch.

even when the deps should be installed using makepkg --syncdeps and libiconv-devel is in the makedepends

Solution

Adding -liconv to the command line is one workaround, changing --with-libiconv-prefix=/usr configure option to --without-libiconv-prefix is another but I am strugging to find a proper cause/solution so far.

I am seeing the same error when building the mingw-w64-cross-binutils package inside completely fresh MSYS2 environment on CI (using https://github.com/msys2/setup-msys2). So this rather seems as a packaging issue in one of the involved MSYS2 packages (most probably libiconv-devel).

Issue

checking for makeinfo... (cached) makeinfo --split-size=5000000
/c/Projekty/MSYS2-packages/mingw-w64-cross-binutils/src/binutils/libctf/configure: line 14872: makeinfo: command not found
configure: WARNING:
*** Makeinfo is too old. Info documentation will not be built.

Solution

Add texinfo to makedepends.

cgudrian commented 10 months ago

I'm currently facing this error myself building a canadian cross compiler on Linux hosted by MinGW and targeting aarch64 using the Linaro build script. In my case libiconv.a is supposed to be pulled in by libtool as a transitive dependency via libintl.a. This mechanism does obviously not work when building libraries for Windows.

Adding -liconv fixed the issued for me as well.

cgudrian commented 10 months ago

The culprit in my special case was the value of LDFLAGS: it contained a linker path entry for the MinGW /usr/lib directory. Because of the convoluted lookup logic the presence of that path leads to /path/to/mingw/usr/lib/libiconv.a being added to libintl.la (which does not work when building for Windows). Leaving MinGW's /usr/lib out of the LDFLAGS leads to -liconv being added to libintl.la (which does work).

Maybe that's the case here as well.
