Writing recipe for Crypto++, and getting build errors

[Adonay Felipe Nogueira <adfeno@openmailbox.org>]

[-- Attachment #1.1: Type: text/plain, Size: 4401 bytes --]

Note: I'm not a programmer, the only thing I can understand is basic
Guile Scheme and basic Bash scripting. So, I'm not really fit to make
changes in the Crypto++'s source files by myself.

I'm writing a recipe for Crypto++ and other packages. I'm not a
programmer, but I decided to try to contribute to Guix by making the
first steps on porting Tahoe-LAFS and related dependencies.

In attachment is the set of recipes I'm writing. The examples given
assume $GUIX_PACKAGE_PATH referring to directories where the
user-supplied recipes can be found.

Doing:

$ guix build --fallback "cryptopp"

... outputs:

# Begin of output
starting phase `build'
make: *** No rule to make target 'dynamic'.  Stop.
phase `build' failed after 0.2 seconds
builder for
`/gnu/store/k863vf0ab6hkdhbm7zgmbfs1c3wdqpqs-cryptopp-5.6.4.drv' failed
with exit code 1
@
build-failed /gnu/store/k863vf0ab6hkdhbm7zgmbfs1c3wdqpqs-cryptopp-5.6.4.drv - 1 builder for `/gnu/store/k863vf0ab6hkdhbm7zgmbfs1c3wdqpqs-cryptopp-5.6.4.drv' failed with exit code 1
guix build: error: build failed: build of
`/gnu/store/k863vf0ab6hkdhbm7zgmbfs1c3wdqpqs-cryptopp-5.6.4.drv' failed
# End of output

However, I did some tests by doing:

$ guix build --fallback --keep-failed "cryptopp"
$ cd "[Failed build path]"
$ sudo --user="[User owner of failed build path]" guix environment
--pure "cryptopp"
$ make "dynamic"

And it **does** start building. If instead of `make "dynamic"`, one does
`make -dnpw "dynamic"` (both in the recipe itself and in the series of
commands given earlier), one can see that:

* The build phase in `guix build` doesn't find the GNUmakefile.

* Attempting the series of commands given earlier, `make` **does** find
the GNUmakefile file.

Besides, someone at #guix suggested me to look at what the NixOS project
did with their Crypto++ package, and it seems they are using it
normally, without removing the dependency on `ldconfig`.

## Additional subject: Absence of `ldconfig`

Seeing the GNUmakefile, it seems to expect some commands to be available
in the environment, so I tried finding those and seeing if the
environment sees them from the profile.

If I remake the environment given before **without** the `--pure`
option, specially if one is using Guix on other distribution, doing:

$ which ar ranlib cp mv egrep chmod mkdir ln ldconfig uname gcc g++ cut
which

... outputs:

# Begin of output
/gnu/store/4bs2xiv9mr0p8vfy046b4jaqn0958wk4-profile/bin/ar
/gnu/store/4bs2xiv9mr0p8vfy046b4jaqn0958wk4-profile/bin/ranlib
/gnu/store/4bs2xiv9mr0p8vfy046b4jaqn0958wk4-profile/bin/cp
/gnu/store/4bs2xiv9mr0p8vfy046b4jaqn0958wk4-profile/bin/mv
/gnu/store/4bs2xiv9mr0p8vfy046b4jaqn0958wk4-profile/bin/egrep
/gnu/store/4bs2xiv9mr0p8vfy046b4jaqn0958wk4-profile/bin/chmod
/gnu/store/4bs2xiv9mr0p8vfy046b4jaqn0958wk4-profile/bin/mkdir
/gnu/store/4bs2xiv9mr0p8vfy046b4jaqn0958wk4-profile/bin/ln
/sbin/ldconfig
/gnu/store/4bs2xiv9mr0p8vfy046b4jaqn0958wk4-profile/bin/uname
/gnu/store/4bs2xiv9mr0p8vfy046b4jaqn0958wk4-profile/bin/gcc
/gnu/store/4bs2xiv9mr0p8vfy046b4jaqn0958wk4-profile/bin/g++
/gnu/store/4bs2xiv9mr0p8vfy046b4jaqn0958wk4-profile/bin/cut
/usr/bin/which
# End of output

This indicates that `ldconfig` is absent. Someone in #guix told me that
it was supposed to be provided by 

Additionally, `which` was included in the output (comes from the
"debianutils" package on .deb-based distributions) and is also absent,
and the GNUmakefile seems to expect `which` at some point (although I'm
not sure if the build process reached that), so the absence of `which`
might be good to discuss on other bug report.


Respectfully, Adonay.
