[Buildroot] Set LIBS variabile using new package format

[Buildroot] Set LIBS variabile using new package format

[Daniele Salvatore Albano]

Hi,

i'm writing some packages for buildroot, i need them for my little
project. Currently i added packages for clamav, with support for
clamd/clamdscan/freshclam, havp, dansguardiand and tinyproxy. For last
two i used the new package format, looking other packages.

However i've a problem: there is a little bug in the tinyproxy
configure so libintl.h is being reknown but -lintl isin't added to
libraries to link and it fails to link so i need to add it. I've tried
setting up LIBS variable, PACKAGENAME_LIBS variable and more but
nothing to do, it doesn't work. I looked for other packages too but
nothing.

There is a way to set change LIBS or CFLAGS variables? Or is better to
do a little patch to apply to configure.ac and use
PACKAGENAME_AUTORECONF to force to rebuild autoconf?

There are docs about this new format?

Best Regards,
Daniele

If it's really a bug in tinyproxy itself, then the best solution is to
write a patch, send it upstream, and while waiting for upstream to make
a new release, include the patch in Buildroot as well.

There's no such thing as PACKAGENAME_LIBS. All the PACKAGENAME_*
variables are documented at the top of package/Makefile.autotools.in.

In your case, PACKAGE_CONF_ENV would quite certainly be the solution, it
allows to set variables passed to the ./configure script.

For example, in bind/bind.mk :

BIND_CONF_ENV = BUILD_CC="$(TARGET_CC)" \
                BUILD_CFLAGS="$(TARGET_CFLAGS)"

As said previously, it depends. If it's a real bug in tinyproxy's
configure, fix it with a patch. If it's a tuning needed due to
Buildroot specific things, then do it with BIND_CONF_ENV.

Sincerly,

Thomas
