Hello,
I want use lcov to generate a coverage report for a C program, but I find out I always need to add "findutils" package to my shell in order for "lcov" to work. Shouldn't "findutils" be added to the propagated-inputs of "lcov", to have it available at runtime?
Here is a short description of the problem which can be tested on the attached (empty) C program "main.c".
1. The shell I want to use:
guix shell -C gcc-toolchain lcov
2. The commands I run in the shell:
gcc -fprofile-arcs -ftest-coverage -g -O0 -c main.c
gcc -fprofile-arcs -ftest-coverage -g -O0 -lgcov main.o -o my_program
./my_program
lcov --directory . --capture --output-file coverage.info
3. The problem I get: lcov is unable to find the .gcda files for its coverage report (message ".geninfo-real: WARNING: no .gcda files found in . - skipping!").
Everything works fine with "guix shell -C gcc-toolchain lcov findutils", or if I add "findutils" to the propagated-inputs of "lcov" as in the proposed patch (for the commit 13e252af79ffb85bc68d8104fdf700269b903875 on master), which I have tested by defining and building the modified package in a local copy of the gnu/packages/code.scm module.
Of coarse I am open to recognize my errors if I have missed something in the package usage :-) or if I have misunderstood the usage of propagated-inputs (but it didn't work with findutils as "normal" input)... or if there are better solutions.
Thank you in advance,
Luca
