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
