Building collectd fails on host with libgcrypt-config

When collectd is built on a machine with libgcrypt-config in $PATH, OpenWRT (trunk) fails to build with the following error:

OpenWrt-libtool: link: mips-openwrt-linux-uclibc-gcc -shared  -fPIC -DPIC  .libs/network_la-network.o .libs/network_la-utils_fbhash.o   -L/usr/lib -L/path/to/openwrt/staging_dir/target-mips_r2_uClibc-0.9.32/usr/lib -L/path/to/openwrt/staging_dir/target-mips_r2_uClibc-0.9.32/lib -L/path/to/openwrt/staging_dir/toolchain-mips_r2_gcc-4.5-linaro_uClibc-0.9.32/usr/lib -L/path/to/openwrt/staging_dir/toolchain-mips_r2_gcc-4.5-linaro_uClibc-0.9.32/lib -lm -lz -lpthread -lgcrypt /usr/lib/ -ldl  -Os -mips32r2 -mtune=mips32r2 -msoft-float -Wl,-rpath-link=/path/to/openwrt/staging_dir/target-mips_r2_uClibc-0.9.32/usr/lib   -Wl,-soname -Wl, -o .libs/

/usr/lib/ could not read symbols: File in wrong format
collect2: ld returned 1 exit status
make[6]: *** [] Error 1

This is because the collectd configure script sets GCRYPT_LDFLAGS="-L$(libgcrypt-config --exec-prefix)/lib" and passes this to ld for the network plugin (

To avoid the error, either explicitly build without libgcrypt (which I assume is intended as it is not listed as a dependency) or set the location to "$(STAGING_DIR)/usr" as with the dependencies of several other plugins. The attached patch implements the former choice.

Please, fix this in backfire branch.

comment:3 Changed 6 years ago by gadget@…

Just to note, the patch posted at /changeset/29854.html breaks (an already broken) compile of collectd, attempting to compile Backfire 10.03.1 on a stock Slackware 13.37 system.

In particular, adding: "--without-libgcrypt" at 154 solves this issue, however,
removing "TARGET_CFLAGS += -Wl,-rpath-link=$(STAGING_DIR)/usr/lib" at 144 creates a new problem in that the dependency on iwinfo is broken.

Solution for me was to apply the addition at 154, and leave intact the deletion at 144.

As an aside, how do we register a username on OpenWRT Trac, as I would be willing to contribute?
