Issues cross-compiling hurd

[Nathan Dehnel]

I am trying to compile hurd with cross-hurd, and I get this compilation
error:

I tried running ./configure LIBS=-lpthread and setting LIBS += -lpthread in
configparms, but I'm not really sure what I'm doing. Any suggestions would
be appreciated.

Hello,
Which source are you taking exactly?

I tried running ./configure LIBS=-lpthread and setting LIBS += -lpthread in
configparms, but I'm not really sure what I'm doing.

The issue is with the header, not the library, so it'd rather be a -I.
But libpthread is supposed to be provided by glibc itself actually, by
using the hurd libpthread repo and adding it as an add-on.

I used the default sources set by cross-hurd in vars.sh:
https://github.com/flavioc/cross-hurd

It doesn't seem to work. Which directory do I include? /usr/include?
./glibc/libpthread/sysdeps/pthread/bits?
./glibc/libpthread/sysdeps/generic/? You're referring to
CFLAGS="-I/directory" ./configure, correct?

libpthread appears to be in the glibc directory, and is getting passed to
configure.
