成功配置后 gnu 报错

Question

我正在尝试构建依赖于 libtiff 的“lcms2”静态库。 libtiff 再次依赖于 libjbig。我已经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

配置没有报错：

checking tiffio.h usability... yes

checking for tiffio.h... yes

当我创建库时，它会抛出以下错误：

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

链接命令中没有对 JBIG 库的引用（我不记得它应该放在之前还是之后 - 有些库需要两者 - 对 libtiff 的引用，-ltiff），所以 jbg_* 引用可以' t得到解决。链接 LCMS 对您没有帮助，因为 JBIG 没有链接到 JBIG，而只是被 JBIG 引用。

在链接命令中添加-ljbig。

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