Question

我正在尝试构建依赖于libtiff的'lcms2'静态库。 libtiff再次依赖libjbig。我已使用以下参数成功配置了libtest：

CFLAGS="-fPIC" CXXFLAGS="-fPIC" LIBS="-ljbig" ./configure --prefix=/usr/local --enable-static=yes --enable-shared=no --with-zlib=yes --with-jpeg=yes --with-tiff=yes --with-pic=PIC

配置报告无错误：

checking tiff.h presence... yes
checking for tiff.h... yes
checking tiffio.h usability... yes
checking tiffio.h presence... yes
checking for tiffio.h... yes

当我创建库时，它会抛出以下错误：

libtool：link：gcc -std = gnu99 -fPIC -o tificc tificc.o xgetopt.o vprf.o ../../src/.libs/liblcms2.a -ltiff -ljpeg -lz -lm

在链接命令中没有引用JBIG库（我不记得它应该在之前或之后 - 一些库需要两者 - 对libtiff的引用，-ltiff），所以{{1} }引用无法解决。连接LCMS对您没有帮助，因为JBIG没有链接，但仅由JBIG引用。

将jbg_*添加到链接命令。

或者，手动编辑Makefile并将-ljbig添加到LIBS（例如LIBS = -ljbig）。

成功配置后gnu出错
