PROTOBUF learning------ubuntu14.04 under protobuf2.6 installation

1 Downloads Protobuf

Https://github.com/google/protobuf/releases/download/v2.6.1/protobuf-2.6.1.tar.gz

2 Enter the directory of the downloaded file

1 tar -zxvf protobuf-2.6. 1. Tar . GZ 2 cd protobuf-2.6. 1/3 ./Configure4make5 make check  6makeinstall

I have the following problems when I execute the./configure

Solutions

sudo Install build-essential

3 Check if the installation is successful

Protoc--version

If the installation succeeds, the version number will appear as

2.6. 1

If there is a problem, the error content will be output

Finally, I completed the installation, with the above command to check the version number when the following problem occurs

Protoc:error while loading shared libraries:libprotocbuf.so.9:cannot open shared

Cause of error

The default installation path for PROTOBUF is/usr/local/lib, and/usr/local/lib is not in the default Ld_library_path of the Ubuntu system, so Lib is not found

Solutions

1 Create the file bprotobuf.conf file in the/etc/ld.so.conf.d/directory, the file content is as follows

/usr/local/lib

2 input commands

sudo ldconfig

Then, enter Protoc--version to see the version number as normal.

For more information about/etc/ld.so.conf.d/, please refer to the following article for instructions
