I'm building s6 from source on latest git tags and it seems to fail because it cannot link execline:
./configure --disable-execline; make # works ./configure; make # fails with message exec gcc -o s6-ftrig-listen -pipe -Wall -std=c99 -fno-exceptions -fno-unwind-tables -fno-asynchronous-unwind-tables -Wa,--noexecstack -ffunction-sections -fdata-sections -O2 -fomit-frame-pointer -fno-stack-protector -Wl,--sort-section=alignment -Wl,--sort-common -Wl,--gc-sections src/pipe-tools/s6-ftrig-listen.o libs6.a.xyzzy -lexecline -lskarnet /home/linuxbrew/.linuxbrew/bin/ld: cannot find -lexecline collect2: error: ld returned 1 exit status make: *** [Makefile:138: s6-ftrig-listen] Error 1 Execline is installed and available. $ ls /usr/lib/execline/ libexecline.a Any clues about how to solve this?
