Problem compiling boost for mysql

Problem compiling boost for mysql

[Emmanuel Medernach]

Hello Guixers,

I have an error when trying to build a package, the following gnu packages
derivation does not compile:

# guix build -e '(@ (gnu packages boost) boost-for-mysql)'

phase `more-bin-sh-patching' succeeded after 0.0 seconds
starting phase `configure'

Any help is appreciated

I'm reproducing the problem, I tried to use boost instead of
boost-for-mysql in the mysql package, but is still requires boost
1.59.0, which is not building.

First because execunix.c got translated into C++, in a later version of 
boost, so the guix recipe to build it changed, see:
02fef9619bd96086aa9255ffb0944d4cda617c84

But boost-for-mysql inherits that configure phase, whereas it still has
the c version of that file.

And second, if you fix^Whack that, then you get a compilation error on
some const * being used as non-const *.

Here is that whitespace-damaged hack:

diff --git a/gnu/packages/boost.scm b/gnu/packages/boost.scm
index 2f2ca289ab..a9b463ca92 100644

                     (out (assoc-ref outputs "out")))
                 (substitute* '("libs/config/configure"
 
"libs/spirit/classic/phoenix/test/runtest.sh"
-                              "tools/build/src/engine/execunix.cpp"
+                              "tools/build/src/engine/execunix.c"
                                "tools/build/src/engine/Jambase")
                   (("/bin/sh") (which "sh")))

I don't know how to fix that properly, maybe copy/paste the whole
(arguments ...) from boost into boost-for-mysql, but that does not
look right.
