你好:我想让我的qtopia core支持jpeg库总是出错 希望你给我指导一下: 首先我在我的linux 2.4里面装了jpeg库 过程如下: ./configure --prefix=/usr/local/arm/3.4.1/arm-linux --host=arm-linux --enable-shared --enable-static; 修改Makefile: CC= /hao/toolchain/arm-linux/bin/arm-linux-gcc AR= /hao/toolchain/arm-linux/bin/arm-linux-ar rc AR2= /hao/toolchain/arm-linux/bin/arm-linux-ranlib make make install 装好了过后我可以编译运行v4l的应用程序可以在板子上面采集视频; 我的qtopia-core 4.2.2的安装也选择了(-system-libjpeg); 我在编译程序的步骤如下: 1。qmake -project 在生成的pro文件里面加入了 LIBS += -L/usr/local/arm/3.4.1/ arm-linux/lib -ljpeg 2。qmake 3。make 然后出错如下: arm-linux-g++ -Wl,-rpath,/usr/local/Trolltech/QtopiaCore-4.2.2-arm/lib -o a a.o main.o moc_a.o -L/usr/local/Trolltech/QtopiaCore-4.2.2-arm/lib -ljpeg -L/usr/local/arm/3.4.1/arm-linux/lib -lQtGui -L/tmp/qtopia-core-opensource-src-4.2.2/lib -lQtNetwork -lQtCore -lm -ldl -lpthread a.o(.text+0xe00): In function `put_image_jpeg(_IO_FILE*, unsigned char*, int, int, int, int)': : undefined reference to `jpeg_std_error(jpeg_error_mgr*)' a.o(.text+0xe18): In function `put_image_jpeg(_IO_FILE*, unsigned char*, int, int, int, int)': : undefined reference to `jpeg_CreateCompress(jpeg_compress_struct*, int, unsigned int)' a.o(.text+0xe44): In function `put_image_jpeg(_IO_FILE*, unsigned char*, int, int, int, int)': : undefined reference to `jpeg_set_defaults(jpeg_compress_struct*)' a.o(.text+0xe54): In function `put_image_jpeg(_IO_FILE*, unsigned char*, int, int, int, int)': : undefined reference to `jpeg_set_quality(jpeg_compress_struct*, int, int)' a.o(.text+0xe68): In function `put_image_jpeg(_IO_FILE*, unsigned char*, int, int, int, int)': : undefined reference to `jpeg_stdio_dest(jpeg_compress_struct*, _IO_FILE*)' a.o(.text+0xe74): In function `put_image_jpeg(_IO_FILE*, unsigned char*, int, int, int, int)': : undefined reference to `jpeg_start_compress(jpeg_compress_struct*, int)' a.o(.text+0xedc): In function `put_image_jpeg(_IO_FILE*, unsigned char*, int, int, int, int)': : undefined reference to `jpeg_write_scanlines(jpeg_compress_struct*, unsigned char**, unsigned int)' a.o(.text+0xef0): In function `put_image_jpeg(_IO_FILE*, unsigned char*, int, int, int, int)': : undefined reference to `jpeg_finish_compress(jpeg_compress_struct*)' a.o(.text+0xef8): In function `put_image_jpeg(_IO_FILE*, unsigned char*, int, int, int, int)': : undefined reference to `jpeg_destroy_compress(jpeg_compress_struct*)' a.o(.text+0xf48): In function `put_image_jpeg(_IO_FILE*, unsigned char*, int, int, int, int)': : undefined reference to `jpeg_write_scanlines(jpeg_compress_struct*, unsigned char**, unsigned int)' collect2: ld returned 1 exit status make: *** [a] Error 1 不知道那个步骤出错了,在这里已经瞎忙了好长时间了!!! 我的邮箱是: bighunter1@163.com
