Common PHP installation error: libjpeg. (

Although PHP installation is sometimes very simple, if there are more than one application, it will be a headache for us to install it! The most common problem is the installation of PHP plug-ins! In fact, whether you are an Apache application or Nginx. PHP installation is not very simple. Although there are a lot of configure on the Internet, it is not necessarily suitable for you, because many of them are directly related.

FirstCommonIsConfigure: error: libjpeg. (a | so) not found

A lot of people are bored.InstallWhy can't I find it? If you cannot find it, you should think that it does not exist in the search location. Otherwise, you will not say not found.

The reason is that most of our software only requires rpm-qa | grep ***

Now there are two duplicate software

[Root @ GFS_Server php-5.2.13] # rpm-qa | grep jpeg
Libjpeg-6b-33
Libjpeg-6b-33
Libjpeg-devel-6b-33

Both 32-bit and 64-bit are installed. You can force Delete two packages and reinstall the 64-bit package. Rpm -- allmatches -- nodeps this method really damages the system and damages you. sometimes, some packages in lib will be forcibly deleted for forcible execution .. so I don't think it is recommended to do this. Repeat it and let it repeat it. It doesn't matter!

YesSolutionThe problem is that it cannot be found, IInstallNow, I have to find out where it is.

[Root @ GFS_Server php-5.2.13] # updatedb
[Root @ GFS_Server php-5.2.13] # locate libjpeg. so
/Usr/lib64/libjpeg. so.62
/Usr/lib64/libjpeg. so.62.0.0
/Usr/lib64/libjpeg. so
/Usr/lib/libjpeg. so
[Root @ GFS_Server php-5.2.13] # locate libjpeg.
/Usr/lib64/libjpeg.
// Data0/software/jpeg-6b/libjpeg.
[Root @ GFS_Server php-5.2.13] #

During compilation, we often see a library file, which is generally named *. a, *. so. If you try to search, you can perform fuzzy search!

The above search actually shows some reasons. The configure general search compilation path is/usr/lib, because php searches for the relevant library files under/usr/lib/by default, and the x64 machine is on: /usr/lib64. then you can directly copy the required library files from/usr/lib64 to/usr/lib.

Remember to execute the following command before configure:

Cp-frp/usr/lib64/libjpeg. */usr/lib/

Usr/bin/install: cannot create regular file '/usr/local/man/man1/c0000.1': No such file or directory
Make: *** [install] Error 1
The system prompts that the directory cannot be found. Since the computer cannot be found, we can find the human brain. We should first create the first
Mkdir/usr/local/man
Mkdir/usr/local/man1 is created.
Make install (success if no error is reported)

Configure: error: libjpng. (a | so) not found

In fact, it is the same as the previous one.

Cp-frp/usr/lib64/libpng */usr/lib/

Configure: error: Cannot find ldap libraries in/usr/lib.

Cp-frp/usr/lib64/libldap */usr/lib/

SimilarErrorThere are a lot of methods, and we have to respond flexibly and analyze specific problems!
