Have spent untold hours today fighting with #gnulib and #autotools only to find out that my problem was a weird shell alias thing. 😭😭

Guix has tools to make your program relocatable, that is, let it run in a location unknown at compile time. This is a really cool feature.

However, it has limitations. You can’t use it on windows (provided you could solve the problem with symlinks…), where this is a big issue.

In the mean time, Gnulib provides an easy way that makes your programs *and libraries* relocatable.

TIL use of gnulib's obstack API on glibc systems adds exported dynamic symbols to final binaries (normally harmless but somewhat unusual thing for programs that don't load plugins).

Even '/bin/ls' has a few of those exported out of a binary:

$ nm -D `which ls` | grep -v '^ '
00000000004c0d40 T _obstack_allocated_p
0000000000534808 D obstack_alloc_failed_handler
00000000004c0bd0 T
...

I think I start to understand how #guile bindings for #gnutls work. Now I just have to paste moar bindings.

I like how it uses #gnulib to do the maintainer things.

Debugging build failures can lead you straight down into rabbit holes... #gnulib #libtasn1 #gnu #gnutls

Spending an inordinate amount of time today working on what I thought would be a quick build fix. I feel like I've gotten substantially better an using autotools this past month, but gnulib-tool continues to be an absolute thorn.
