环境

Red Hat Enterprise Linux (RHEL)
- 7.x

问题

We tried to compile postgresodbc driver in Red Hat Enterprise Linux 7.4 64-bit. It got failed with below error:

Raw

checking if : is a manifest tool... no
checking how to run the C preprocessor... /usr/bin/cpp
configure: error: in `/path/to/driver/psqlodbc9/psqlodbc-09.03.0100':
configure: error: C preprocessor "/usr/bin/cpp" fails sanity check

决议

Be aware that 32-bit version of gcc is not shipped by Red Hat in RHEL 7.0 or above. However, refer to the gcc 64-bit installation step below.

Make sure to install gcc-c++ and gcc on the system, provided by gcc-c++ and gcc packages respectively. The yum install command must be run as root user.

Raw

# yum install gcc gcc-c++

诊断步骤

To check if the gcc command exists.

Raw

$ which gcc
/usr/bin/gcc

$ rpm -qf /usr/bin/gcc
gcc-4.8.5-11.el7.x86_64
