Friend of mine was trying to build couchdb today and ran into a problem.
checking jsapi.h usability... no
checking jsapi.h presence... no
checking for jsapi.h... no
checking js/jsapi.h usability... no
checking js/jsapi.h presence... no
checking for js/jsapi.h... no
configure.jm: error: Could not find the jsapi header.
Are the Mozilla SpiderMonkey headers installed?
But he clearly had Mozilla Spidermonkey installed:
- locate jsapi.h
He was stumped and asked me to take a look. I looked at the
config.log and found:
configure.jm:16700: checking jsapi.h usability
configure.jm:16717: g++ -c -DXP_UNIX
-I/usr/local/include -I/usr/include conftest.cpp >&5
./configure.jm: line 16718: g++: command not found
You're using AC_PROG_CXX in your configure.ac to find a C++ compiler.
Unfortunately due to a bug (or misfeature) of autoconf if AC_PROG_CXX
follows AC_PROG_CC then it won't fail if no C++ compiler is found.
Fortunately, it's relatively easy to work around this. You can simply
test that the ac_ct_CXX shell variable is set after running
AC_PROG_CXX. I've attached a patch that does so.
Running configure on a system without a C++ compiler now results in
checking for g++... no
checking for c++... no
checking for gpp... no
checking for aCC... no
checking for CC... no
checking for cxx... no
checking for cc++... no
checking for cl.exe... no
checking for FCC... no
checking for KCC... no
checking for RCC... no
checking for xlC_r... no
checking for xlC... no
checking whether we are using the GNU C++ compiler... no
checking whether g++ accepts -g... no
checking dependency style of g++... none
checking that we found a C++ compiler... no
configure: error: A C++ compiler is required.
