[zeromq-dev] Configure build for 32 bit libray on 64 bit CentOS 7

[Igor Lopez]

Hi,

I am having a dependency problem.

The Quartus Prime and the ModelSim applications requires a bunch of 32 bit
libraries to be installed on the Linux machine for them to work.
Of course is one of them the 0MQ libray libzmq3 and I have not found any
CentOS repositories with that library so I have to build it myself.

First time for me doing a build for another architecture with google giving
the advice on how to configure it gave me this:
$ ./configure --build=i686-pc-linux-gnu "CFLAGS=-m32" "CXXFLAGS=-m32"
"LDFLAGS=-m32"

That will however not work:

checking for gcc... gcc
checking whether the C compiler works... no
configure: error: in `/home/igor/Tools/libzmq':
configure: error: C compiler cannot create executables
See `config.log' for more details


And opening the config.log gives me no understandable hint but it points
out these warnings/errors:

configure:4253: checking whether the C compiler works
configure:4275: gcc -m32 -m32 conftest.c >&5
/usr/bin/ld: cannot find crt1.o: No such file or directory

| return 0;
| }
configure:4322: error: in `/home/igor/Tools/libzmq':

See `config.log' for more details

A standard ./configure will however work.

Hi,

Did you install the 32 tool chain, build essential and so on?

I'm not a big user of centos so I'm not sure how multiarch is handled there

I thought so but I did a
sudo yum install glibc-devel.i686 libstdc++-devel.i686
just to be sure and lo and behold
The configure now goes thru and make is doing its thing.

Thanks for the pointer.

Hi,

the key message is:

/usr/bin/ld: skipping incompatible /usr/lib64/libc.so when searching for -lc

That means you have only 64bit version of libc installed. According
your flags you're trying to build 32bit version, so you must install
32bit libc - glibc.i686
