编译FLTK时Errors汇总

安装fltk-1.3.3-source.tar.gz时，出现的错误汇总：

错误一：

sudo tar -xvf fltk-1.3.3-source.tar.gz

cd fltk-1.3.3

sudo ccmake ./

sudo make

安装到22%，报错如下：

….

[ 21%] Building C object png/CMakeFiles/fltk_png.dir/pngread.c.o

              from /install/fltk-1.3.3/src/Fl.cxx:48:

/install/fltk-1.3.3/FL/fl_utf8.h:62:27: fatal error: X11/Xlocale.h: No such file or directory

compilation terminated.

make[2]: *** [src/CMakeFiles/fltk.dir/Fl.cxx.o] Error 1

make[1]: *** [src/CMakeFiles/fltk.dir/all] Error 2

make: *** [all] Error 2

错误原因：缺少Xlib.h，可以通过命令：apt-file search Xlib.h搜索一下，可知其包含在package libx11-dev中。

解决方法： 安装libx11-dev则可：

sudo apt-get install libx11-dev

装完后，进入fltk-1.3.3目录，继续刚刚中断的编译：

sudo make

错误二：

这个问题是在开启了编译shared libraries时，才会出现。也就是说在CMake里，你ON了红色部分：

CMAKE_BUILD_TYPE               *Debug

CMAKE_INSTALL_PREFIX           */usr/local/fltk-1.3.3

OPTION_ARCHFLAGS               *   

OPTION_BUILD_EXAMPLES          *ON  

OPTION_BUILD_SHARED_LIBS       *ON       

OPTION_CAIRO                   *OFF              

OPTION_CAIROEXT                *OFF   

OPTION_CREATE_LINKS            *OFF        

OPTION_LARGE_FILE              *ON   

OPTION_OPTIM                      *   

OPTION_USE_GL                  *ON   

OPTION_USE_POLL                *OFF   

OPTION_USE_SYSTEM_LIBJPEG      *ON        

OPTION_USE_SYSTEM_LIBPNG       *ON               

OPTION_USE_SYSTEM_ZLIB         *ON            

OPTION_USE_THREADS             *ON         

OPTION_USE_XCURSOR             *ON       

OPTION_USE_XDBE                *ON                              

OPTION_USE_XFIXES              *ON

OPTION_USE_XFT                 *ON

OPTION_USE_XINERAMA            *ON

解决方法：设置OPTION_BUILD_SHARED_LIBS 为OFF即可。

错误三：

test@test:/usr/local/src/Mesa_build$ sudo make

CDPATH="${ZSH_VERSION+.}:" && cd /install/Mesa-10.3.5 && /bin/bash /install/Mesa-10.3.5/bin/missing aclocal-1.14 -I m4

/install/Mesa-10.3.5/bin/missing: line 81: aclocal-1.14: command not found

WARNING: 'aclocal-1.14' is missing on your system.

     You should only need it if you modified 'acinclude.m4' or

     'configure.ac' or m4 files included by 'configure.ac'.

     The 'aclocal' program is part of the GNU Automake package:

     <http://www.gnu.org/software/automake>

     It also requires GNU Autoconf, GNU m4 and Perl in order to run:

     <http://www.gnu.org/software/autoconf>

     <http://www.gnu.org/software/m4/>

     <http://www.perl.org/>

make: *** [/install/Mesa-10.3.5/aclocal.m4] Error 127

错误原因： timestamp skew，从服务器下载来的安装包在本地解压缩文件时时间戳被修改。

解决方法：

在解压后的源文件目录下，

sudo autoreconf -ivf

然后重新编译安装源文件，错误消失。

错误四：（gcc 4.6.4）

解决方法：

sudo gedit ../src/Fl_JPEG_Image.cxx

Replace this function declaration (in both 158 and 340 line) as:

jpeg_read_header(&dinfo, 1);              //the original

with

jpeg_read_header(&dinfo, TRUE);      //the changed
