Arch Linux User Repository

This package is currently unusable / unbuilable due to the __morecore and __after_morecore_hook malloc hooks and the default implementation __default_morecore having been removed from the glibc API. (https://github.com/libhugetlbfs/libhugetlbfs/issues/62)

I encourage you to deal with upstream directly. One of the Arch practices is that users should communicate with project developers more actively. This just saves a lot of time to everyone. Ok, I went ahead and created fix/pull request to the upstream project. A proper upstream fix is definitely better than carrying Arch specific hacks.

It's only reserved since C99. Since you are happy to sed the Makefile for other purposes, adding the following to your prepare stanza makes sense until upstream fixes the issue (either by renaming the variable or specifying the required standard in cflags): sed 's/CFLAGS +=/CFLAGS += -std=gnu90/' -i Makefile

"restrict" is a reserved word in C language. Upstream should not use it for variable names. Please contact upstream and report this error.

My build fails with: Makefile:138: *** LIB32 (/usr/lib to /usr/lib) and LIB64 (/usr/lib64 to /usr/lib) are resolving to the same place. Manually specify LIB32 and LIB64. e.g. make PREFIX=/usr LIB32=lib32 LIB64=lib64. Stop.
