Fixing PHP Compilation Failures and ld/ldconfig Issues on CWP with CentOS 8/AlmaLinux 8

Fixing PHP Compilation and ld/ldconfig Issues on CWP (CentOS 8 / AlmaLinux 8)

 

CentOS Web Panel (CWP) is a powerful hosting control panel, but when installed on CentOS 8 or AlmaLinux 8, some users face annoying problems like PHP compilation failures or strange ld / ldconfig behavior. These issues often arise due to outdated toolchains, missing development libraries, or broken shared library links.

Why Does PHP Compilation Fail?

• Outdated GCC or binutils: Older versions of compilers or linkers can break PHP builds.
• Missing Development Tools: Libraries like libxml2-devel or libpng-devel are crucial.
• Broken ld/ldconfig: Damaged symlinks or misconfigured library paths.
• Conflicting Repositories: Misconfigured Remi or EPEL repositories causing version clashes.

Step-by-Step Solutions

1. Update Toolchain and Dev Tools

sudo dnf update -y
sudo dnf groupinstall "Development Tools" -y
sudo dnf install gcc gcc-c++ make automake autoconf libtool -y
sudo dnf install binutils binutils-devel -y
ld --version

2. Repair ldconfig Links

sudo ldconfig
sudo /sbin/ldconfig -v

Ensure /etc/ld.so.conf.d/ contains:

/usr/local/lib
/usr/lib64

3. Install PHP Build Dependencies

sudo dnf install libxml2-devel bzip2 bzip2-devel curl-devel \
libjpeg-devel libpng-devel libXpm-devel freetype-devel \
gmp-devel mariadb-devel aspell-devel recode-devel \
libicu-devel oniguruma-devel sqlite-devel libxslt-devel zip unzip

4. Clean and Recompile PHP

cd /usr/local/src
rm -rf php*
sh /scripts/php-selector recompile 8.1

5. Fix ld if Corrupted

sudo dnf reinstall binutils
sudo ln -sf /usr/bin/ld.bfd /usr/bin/ld

Conclusion

By updating your build toolchain, repairing ldconfig, and installing the right libraries, you can easily fix PHP compilation issues and ld errors on CWP running CentOS 8 or AlmaLinux 8.
