Hello, I need mysql-devel to compile few packages on my server but looks like its not included with plesk 10. I am running CentOS 5.6 . I tried to install using yum but before that I added parellel's centos respository.. I am receiving following error: yum install mysql-devel Code: ---> Package mysql-devel.x86_64 0:5.1.59-1.el5.art set to be updated --> Processing Dependency: libndbclient.so.3()(64bit) for package: mysql-devel --> Processing Conflict: mysql conflicts MySQL --> Finished Dependency Resolution mysql-devel-5.1.59-1.el5.art.x86_64 from atomic has depsolving problems --> Missing Dependency: libndbclient.so.3()(64bit) is needed by package mysql-devel-5.1.59-1.el5.art.x86_64 (atomic) mysql-5.5.14-11071510.x86_64 from installed has depsolving problems --> mysql conflicts with mysql Error: mysql conflicts with mysql Error: Missing Dependency: libndbclient.so.3()(64bit) is needed by package mysql-devel-5.1.59-1.el5.art.x86_64 (atomic) You could try using --skip-broken to work around the problem You could try running: package-cleanup --problems package-cleanup --dupes rpm -Va --nofiles --nodigest The program package-cleanup is found in the yum-utils package. Here are my questions: 1. Is it safe to install mysql-devel this way, won't it interfere with my current installation ? 2. If safe, then how to resolve above problem ? Thank you! PS: This is my first post here, if any mistake in then please pardon me for that !
