Question: how do I correctly include libint2.h in pure C code? #105

Closed zc62 closed 6 years ago

I am using release 2.4.2. While I am compiling a piece of pure C code that uses libint2, I got a compilation error:

In file included from /home/xxx/local/include/libint2/libint2_types.h(25),
                 from /home/xxx/local/include/libint2/util/generated/libint2_types.h(26),
                 from /home/xxx/local/include/libint2.h(35),
                 from /home/xxx/source/include/xxxxx.h(12),
                 from /home/xxx/source/xxxxxxxxxxxx.c(18):
/home/xxx/local/include/libint2/util/memory.h(24): catastrophic error: cannot open source file "cstdlib"

I found this memory.h is in pure C++. Did I do anything wrong? I think libint2.h is intended to be C-compatible?

sorry, C got broken due to missing tests. This is resolved via 449621140fc3322d9a8e51581c2b3900cb66d4ad ... will make 2.5.0-beta.2 shortly
