233046 - configure does not detect gcc on solaris

Status: RESOLVED INACTIVE

(NSS :: Build, defect)

Description

[Vladimír Marek]

User-Agent:       
Build Identifier: 

After running ./configure, it detects wrongly that I have CC compiler (?)
instead of gcc.

Reproducible: Always
Steps to Reproduce:
1. Download and unpack nss-3.9.tar.gz
2. cd nss-3.9/mozilla/nsprpub
3. ./configure
Actual Results:  
bash-2.05$ ./configure 
loading cache ./config.cache
checking host system type... sparc-sun-solaris2.9
checking target system type... sparc-sun-solaris2.9
checking build system type... sparc-sun-solaris2.9
checking for whoami... /usr/ucb/whoami
checking for c++... CC
checking whether the C++ compiler (CC  ) works... no
configure: error: installation or configuration problem: C++ compiler cannot
create executables.


Expected Results:  
find and configure build with gcc compiler

conifg.log:
configure:621: checking host system type
configure:642: checking target system type
configure:660: checking build system type
configure:1021: checking for whoami
configure:1840: checking for c++
configure:1872: checking whether the C++ compiler (CC  ) works
configure:1888: CC -o conftest    conftest.C  1>&5
./configure: CC: not found
configure: failed program was:

#line 1883 "configure"
#include "confdefs.h"

int main(){return(0);}

However configure can be persuaded using gcc by running:
CXX=g++ CC=gcc ./configure

Thanks for the bug report.

Do you only want to build NSPR?  Or do you want to build
NSS and have to build NSPR first because it's a dependency?

On Solaris, both NSS and NSPR use the Sun compilers (cc and
CC) by default.  This default is different from autoconf's
default and simply reflects our different development
environment.

To build NSS with gcc, you need to specify
the make variable NS_USE_GCC=1.  This will also cause NSPR
to be built with gcc.

To build NSPR (standalone) with gcc, you need to say
    CXX=g++ CC=gcc ./configure
as you discovered.

The only thing I can do about this bug is to enhance NSPR's
configure script so that it detects gcc if the default cc
is not found.

I would like to apologise for not reading build instructions properly first.
Yes, I'm tryig to build whole NSS. Detection of gcc when cc is not found would
be nice, but since whole nss is not driven by autoconf script, it will not help
much, I think.

[Wan-Teh Chang]

The steps to build the whole NSS on Solaris with gcc are
as follows.

1. cd mozilla/security/nss
2. gmake nss_build_all NS_USE_GCC=1

Step 2 produces a debug build.  If you want an optimized
build, say:

2a. gmake nss_build_all NS_USE_GCC=1 BUILD_OPT=1

You can set NS_USE_GCC and BUILD_OPT as environment variables.

Please let me know if these steps works for you.

i intend to install opensolaris today/tomorrow, i expect to mark this bug as worksforme. although nrubsig already runs it, so he could check sooner, since i'll be spending my time w/ setup.
