buildroot compilation fails with glibc-2.28

[acarno]

I'm building the freedom-u-sdk on Arch Linux, which ships with glibc-2.28. Compilation breaks while building buildroot:

This is a known problem for buildroot; it stems from having to build m4, which in turn has an old version of gnulib. I believe the buildroot folks patched this in a more recent version -- see here.

It also affects bison, as described here.

The easiest solution problem involves upgrading the buildroot version shipped with the SDK; once I've got the current version working (by applying the patches), I'll try to spend some time seeing how tricky upgrading buildroot would be.

Hello, i have a similar problem 👍 `$ make C:/Program Files/Git/mingw64/bin/make.exe all-recursive make[1]: Entering directory 'C:/Program Files/httpd-2.4.41/srclib/m4'

Making all in . /usr/bin/sh: line 20: C:/Program: No such file or directory

make[1]: *** [Makefile:1506: all-recursive] Error 1 make[1]: Leaving directory 'C:/Program Files/httpd-2.4.41/srclib/m4' make: *** [Makefile:1461: all] Error 2 ` What did i do wrong? or it's a bug?

This does not look related to the earlier problem. Please create new issues for new problems.

You are building on a windows machine, and windows likes to put spaces in directory names and file names. But Unix based programs don't like that because space is used as a delimiter in shell and make and lots of other places. It is best to create a directory at top level to hold unix based programs like mingw64, and don't use spaces for any dir name or file name.
