Se você usa o php ver. 5.4 ou acima, como nesta situação. Pacote real aqui link
Você pode instalá-lo via pecl:

Boa sorte!
Eu estou tentando instalar a extensão PHP xdiff no Debian com Apache 2 e PHP Versão 5.4.44, mas não consigo está funcionando.
Eu tentei o seguinte
pecl install xdiff
Mas tenho erros:
[…]

configure: error: Please reinstall the libxdiff distribution
ERROR: '/tmp/pear/temp/xdiff/configure --with-xdiff' failed
Depois disso, instalei re2c
com
apt-get install re2c
Agora eu recebo:
checking for re2c... re2c
checking for re2c version... 0.13.5 (ok)
checking for gawk... no

configure: error: Please reinstall the libxdiff distribution
ERROR: '/tmp/pear/temp/xdiff/configure --with-xdiff' failed
Eu acho que tenho que instalar o libxdiff
, mas como faço isso?
[UPDATE]
Como não consigo encontrar nenhuma fonte que eu possa compilar por mim mesmo, tentei converter O pacote rpm do Fedorer com alian
.
apt-get install alian
wget ftp://ftp.muug.mb.ca/mirror/fedora/linux/releases/20/Everything/x86_64/os/Packages/l/libxdiff-1.0-3.fc20.x86_64.rpm
alian libxdiff-1.0-3.fc20.x86_64.rpm
dpkg -i libxdiff-1.0-3.fc20.x86_64.deb
Embora o processo de instalação não tenha lançado nenhum erro, tentando instalar xdiff
com pecl
, recebi o mesmo erro mencionado acima.
[ATUALIZAÇÃO 2] Eu tentei compilar da seguinte forma:
curl -O http://www.xmailserver.org/libxdiff-0.23.tar.gz
tar -xzf libxdiff-0.23.tar.gz
cd libxdiff-0.23/
./configure
make
make install
Mas recebo erros:
