PKG_CONFIG_PATH cairo.pc não pode encontrar pixman

Question

seguindo esta instrução: link

Eu instalei o cairo e o pixman, mas o cairo não pode encontrar o pixman.

Package pixman-1 was not found in the pkg-config search path.
Perhaps you should add the directory containing 'pixman-1.pc'
to the PKG_CONFIG_PATH environment variable
No package 'pixman-1' found
gyp: Call to 'pkg-config pixman-1 --libs' returned exit status 1. while trying to load binding.gyp

meu cairo.pc tem esta aparência:

prefix=/usr
exec_prefix=${prefix}
libdir=${exec_prefix}/lib
includedir=${prefix}/include

Name: cairo
Description: Multi-platform 2D graphics library
Version: 1.12.14

Requires.private:   gobject-2.0 glib-2.0      pixman-1 >= 0.30.0    fontconfig >= 2.2.95 freetype2 >= 9.7.3   libpng xrender >= 0.6 x11
xext
Libs: -L${libdir} -lcairo
Libs.private:           -lz -lz
Cflags: -I${includedir}/cairo

veja agora o que acontece quando edito o PKG_CONFIG_PATH ...

com:

PKG_CONFIG_PATH=/opt/X11/lib/pkgconfig



[root@vps ~]# npm install canvas
npm http GET https://registry.npmjs.org/canvas
npm http 304 https://registry.npmjs.org/canvas

Answer 1

Graças à sua pergunta, encontrei minha solução.

[server]$ ./configure --prefix=$HOME/test
[server]$ make
[server]$ make install
[server]$ ls -R ~/test/
~/test/:
include  lib

~/test/include:
pixman-1

~/test/include/pixman-1:
pixman-version.h  pixman.h

~/test/lib:
libpixman-1.a   libpixman-1.so    libpixman-1.so.0.32.4
libpixman-1.la  libpixman-1.so.0  pkgconfig

~/test/lib/pkgconfig:
pixman-1.pc

Tudo o que eu pedi foi

$ export PKG_CONFIG_PATH="$HOME/lib/pkgconfig/"

então o pkg-config pixman-1 --libs retornou a biblioteca correta e eu pude fazer o cairo compilar.

Talvez haja um problema com o pkg-config encontrar pixman: você pode tentar configurar as variáveis de ambiente para sobrescrever o pkg-config

pixman_CFLAGS - C compiler flags for pixman, overriding pkg-config

pixman_LIBS - linker flags for pixman, overriding pkg-config

$ export pixman_CFLAGS="-I$HOME/include/pixman-1"
$ export pixman_LIBS="-L$HOME/lib/ -lpixman-1"

Answer 2

Copie simplesmente pixman.h e pixman-version.h da pasta pixman-1 para a pasta superior que é incluir .

Agora você pode executar o comando make e ele funciona como um encanto.

    

Answer 3

Você precisará instalar as bibliotecas de desenvolvimento do pixman - que essas instruções parecem ter deixado de fora.

# apt-get install libpixman-1-dev
