[gnutls-help] Cannot build gnutls from source: picks the wrong libnettle

[Sebastien Decugis]

Hello,

I am trying to build latest gnutls from source, and I encounter an issue. My system is Ubuntu Precise.

I have installed all dependencies as described in README-alpha.
In addition, I have built from source and installed under my home folder the latest automake and nettle.

[Side comment, when I ran "make bootstrap" I encountered an issue already reported here about missing src/libopts/Makefile.in, and I had to run "autoreconf -fvi" to fix it. Is it normal? It could be worth writing this in the README-alpha file...]


I am now encountering an error when I try to make GNUTLS:
make[4]: Entering directory `/home/thedoc/sources/gnutls-latest/src/crywrap'

It seems that the ./configure script is correctly following my NETTLE_LIBS=-L/home/user/bin/nettle/lib/ instruction (when I don't add it, I cannot configure successfully), but somehow the value is not propagated to the crywrap Makefile. I also tried to add LDFLAGS= and LD_LIBRARY_PATH= but got the same issue. The complete configure line I am using is:

LD_LIBRARY_PATH=/home/user/bin/nettle/lib/ LDFLAGS=-L/home/user/bin/nettle/lib/ NETTLE_LIBS=-L/home/user/bin/nettle/lib/ HOGWEED_LIBS=-L/home/user/bin/nettle/lib/ NETTLE_CFLAGS=-I/home/user/bin/nettle/include HOGWEED_CFLAGS=-I/home/user/bin/nettle/include ./configure

Has someone encountered the same situation? Do I have to actually replace the nettle lib from my system ?

Best regards,
Sébastien.
