将静态lib（potracelib）与另一个lib链接起来，在Makefile.am中写什么？(Linking static lib (potracelib) with another lib, what to write in Makefile.am?)

我需要链接libpotrace并将其编译成libgerbv。 我应该在Makefile.am中写什么？ 我尝试了各种各样的东西，比如LDADD，LIBDIR，LDFLAGS等，但我没有成功。

我的结构如何：

gerbv / gerbv-test - >来自git，master brach的文件 gerbv / libs / potrace / potrace-test - > potrace - >来自sourceforge.com的文件，最新版本

我使用Debian Jessie，我可以单独编译这两个程序，我都没想到，我怎样才能将potrace链接到gerbv并编译它。头文件（.h）已正确包含，但我没有成功链接.so或.a / la lib。即使在/ usr / local / lib或/ usr / lib中安装了potrace也没有成功。

任何人都能指导我吗？ 如果您可以下载这两个程序，编译它没有错误然后将您输入的内容写入gerbv / src / makefile.Am，那将是最好的。 更新我下载了干净的版本，只做这个修改：

/root/NBP/gerbv/gerbv-test/src/Makefile.am

添加

libgerbv_la_LIBADD = libpotrace.la # src/Makefile.am:84: error: use 'libgerbv_la_LIBADD', not 'libgerbv_la_LDADD' libgerbv_la_LIBDIR = /root/NBP/gerbv/libs/potrace/potrace-old/src/.libs #libgerbv_la_DEPENDENCIES = libpotrace.la

/root/NBP/gerbv/gerbv-test/src/exportimage.c

添加在顶部

#include "../../libs/potrace/potrace-test/src/potracelib.h"

添加到void exportimage_render_to_surface_and_destroy（...）中，如果共享库已正确链接，这将测试。 exportimage.c是libgerbv的一部分，我需要包含libpotrace。

char *v = potrace_version();

做完这个修改后，我通过以下方式构建它

libpotrace root:~/NBP/gerbv/libs/potrace/potrace-test# autoreconf && ./configure --with-libpotrace && make

运行没有问题......

gerbv检察/ libgerbv root:~/NBP/gerbv/gerbv-test# autoreconf && ./configure && make

结果如下：

... make[3]: Entering directory '/root/NBP/gerbv/gerbv-test/src' make[3]: *** No rule to make target 'libpotrace.la', needed by 'libgerbv.la'. Stop. make[3]: Leaving directory '/root/NBP/gerbv/gerbv-test/src' Makefile:498: recipe for target 'all' failed make[2]: *** [all] Error 2 make[2]: Leaving directory '/root/NBP/gerbv/gerbv-test/src' Makefile:472: recipe for target 'all-recursive' failed make[1]: *** [all-recursive] Error 1 make[1]: Leaving directory '/root/NBP/gerbv/gerbv-test' Makefile:401: recipe for target 'all' failed make: *** [all] Error 2

I need to link libpotrace and compile it into libgerbv. What should I write in Makefile.am? I tried various things like LDADD, LIBDIR, LDFLAGS etc., but I was not successful.

How my structure look like:

gerbv/gerbv-test -> files from git, master brach gerbv/libs/potrace/potrace-test -> potrace -> files from sourceforge.com, latest release

I use Debian Jessie, I can compile both programs separately, both I did not figured out, how can I link potrace to gerbv and compile it. The header file (.h) is included properly, but I haven't had any success with linking .so or .a/la lib. Even no success with installed potrace in /usr/local/lib or /usr/lib.

Can anyone direct me? The best will be if you can download both programs, compile it without error and then write what you put into the gerbv/src/makefile.Am. UPDATED I dowloaded clean releases and did this ONLY this modifies:

/root/NBP/gerbv/gerbv-test/src/Makefile.am

added

/root/NBP/gerbv/gerbv-test/src/exportimage.c

added at the top

#include "../../libs/potrace/potrace-test/src/potracelib.h"

added into void exportimage_render_to_surface_and_destroy(...), this will test, if the shared lib is properly linked. exportimage.c is part of libgerbv where I need to include libpotrace.

char *v = potrace_version();

After doing this modifications I build it via:

libpotrace root:~/NBP/gerbv/libs/potrace/potrace-test# autoreconf && ./configure --with-libpotrace && make

runs without a problem...

gerbv/libgerbv root:~/NBP/gerbv/gerbv-test# autoreconf && ./configure && make

This results with:
