我试图为Panotools编译手臂。我编译了所有依赖库(TIFF,ZLIB,JPEG),但是Panotools' configure
在libtiff上失败了:
检查TIFF支持...
configure:tiff home设置为/ usr / local
检查tiff.h可用性......是的 检查tiff.h存在...是的 检查tiff.h ...是的 在-ltiff中检查TIFFOpen ...没有
检查TIFF包是否完整......否 - 某些组件测试失败
配置:错误:
必须在您的系统上安装tiff库 但配置无法找到它。
正如您所见,它可以找到tiff.h
,并且查看config.log
似乎它也找到了库但由于某些未定义的引用而失败。这里有一些日志:

Here某人有同样的问题,但由于不同的原因(根本无法找到libtiff)。并且here它说jbig
是libtiff
的依赖库,所以我尝试将它包含在编译器中(虽然here它没有作为依赖库提及并没有改变。
为什么我会收到那些未定义的引用?这些符号在哪里定义?我需要添加到链接器的任何库吗?
答案 0 :(得分:0)
所有这些未定义的引用都属于库math
,因此只需将其包含在链接器中即可。运行configure
时将其添加到编译命令:
LDFLAGS=-lm
