directfb + gtk 移植到arm平臺

allenflydown

最近在搭建dfb+gtk for arm

參考網(wǎng)路上各路高手的一些經(jīng)驗，基本上把所需要的庫都交叉編譯了，到最后交叉編譯gtk+時遇到問題了

編輯了個configure腳本：

運行報錯

checking for DirectFB... configure: error:
*** DirectFB 0.9.24 or newer and the cairo backend
*** are required. The latest version of DirectFB is always available
*** from http://www.directfb.org/.

于是檢查config.log
發(fā)現(xiàn)問題 configure:33857: error:
回頭看configure文件，導(dǎo)致出錯的原因在于這一行

  if $PKG_CONFIG --atleast-version $DIRECTFB_REQUIRED_VERSION directfb && $PKG_CONFIG --exists cairo-directfb ; then
....

在終端檢測了一下，directfb.pc 是沒有問題的，返回成功，但是 cairo-direcfb.pc 就檢測失敗了

打印錯誤信息：
root@ubuntu:/home//gtk+-2.10.14# pkg-config --exists cairo-directfb --print-errors
Package /opt/armhome/lib/pkgconfig was not found in the pkg-config search path.
Perhaps you should add the directory containing `/opt/armhome/lib/pkgconfig.pc'
to the PKG_CONFIG_PATH environment variable
Package '/opt/armhome/lib/pkgconfig', required by 'cairo', not found


于是看了下cairo-direcfb.pc 和 cairo.pc這兩個文件

發(fā)現(xiàn)cairo-directfb 需要cairo

而cairo.pc中出現(xiàn)了很奇怪的一個依賴


prefix=/opt/armhome
exec_prefix=${prefix}
libdir=${exec_prefix}/lib
includedir=${prefix}/include

Name: cairo
Description: Multi-platform 2D graphics library
Version: 1.4.10

Requires.private: freetype2 >= 8.0.2 fontconfig directfb /opt/armhome/lib/pkgconfig
Libs: -L${libdir} -lcairo
Libs.private: -lz -lm
Cflags: -I${includedir}/cairo


問題就處在這里了，需要/opt/armhome/lib/pkgconfig.pc文件，我也不知道這個東西是什么，卡在這里了，把這個依賴直接去掉的話，會出現(xiàn)

/opt/crosstool/gcc-4.0.1-glibc-2.3.5/arm-unknown-linux-gnu/lib/gcc/arm-unknown-linux-gnu/4.0.1/../../../../arm-unknown-linux-gnu/bin/ld: warning: libpangoft2-1.0.so.0, needed by /opt/armhome/lib/libpangocairo-1.0.so, not found (try using -rpath or -rpath-link)

看來還是cairo庫有問題，但是真的找不到問題出在那里��！求助大俠幫忙分析

T-Bagwell

看來是沒有找到FreeType和FontConfig

不是說缺少pkgconfig.pc
pkgconfig是目錄，如果是desktop的話一般在/usr/lib/pkgconfig目錄下，下面是各種軟件包的.pc文件。你應(yīng)該是freetype2.pc，fontconfig.pc等有問題

我現(xiàn)在覺得以前編譯的庫有問題，又得從頭來了，有一個疑問
從glib開始
在編譯這個庫之前，我設(shè)置了環(huán)境變量
export PREFIX=/opt/armhome
export LD_LIBRARY_PATH=$PREFIX/lib
export PKG_CONFIG_PATH=$LD_LIBRARY_PATH/pkgconfig
export COMPILER=arm-linux-gcc
export HOST=arm-linux


建立文件 arm-linux.cache
配置內(nèi)容如下：
glib_cv_stack_grows=no
glib_cv_uscore=no
ac_cv_func_posix_getpwuid_r=no
ac_cv_func_posix_getgrgid_r=no

CC=$COMPILER ./configure --host=arm-linux --prefix=/opt/armhome --cache-file=arm-linux.cache



報錯如下：
/usr/bin/pkg-config: error while loading shared libraries: /opt/armhome/lib/libglib-2.0.so.0: ELF file OS ABI invalid
configure: error: *** pkg-config too old; version 0.16 or better required.

實際上系統(tǒng)上的pkg-config版本是0.22的
如果我unset  LD_LIBRARY_PATH
就可以編譯通過
我覺得是不是一開始就錯了呢，pkg-config需要交叉編譯成arm版本的呢， 還是用系統(tǒng)安裝的呢？

T-Bagwell

交叉

allenflydown

好像看過一個帖子，說是pkg-config不可以交叉編譯到arm上哦，呵呵

T-Bagwell

誰說的？

allenflydown

忘記誰說的了

T-Bagwell

那就等于沒有
嵌入式和pc沒有什么區(qū)別的
尤其是應(yīng)用程序

allenflydown

自己編譯了下pkg-config,是i386的，不是arm的，指定PKG_CONFIG ,交叉編譯好象沒什么影響啊
