尝试编译 libptrace ( http://sourceforge.net/projects/libptrace/ )。该项目没有宣传任何请求支持的首选方式（不幸的是，该项目没有指出获得帮助的最佳方式）。Anywho，我遇到的问题如下：
% ./build.sh
% ...[SUCCESS]
% ./configure
% ...[SUCCESS]
% make
Making all in src
make[2]: Entering directory `/home/xxx/build/libptrace-git.git/src'
make[2]: *** No rule to make target `../lib/libgnu.la', needed by `libptrace.la'. Stop.
make[2]: Leaving directory `/home/xxx/build/libptrace-git.git/src'
make[1]: *** [all-recursive] Error 1
make[1]: Leaving directory `/home/xxx/build/libptrace-git.git'
make: *** [all] Error 2

如果你用谷歌搜索 libptrace 和 libgnu.la，你会得到零命中。在源代码中寻找它，从 git 中取出新鲜的，你会得到：
% grep -sre libgnu.la *
src/Makefile.in:libptrace_la_DEPENDENCIES = ../lib/libgnu.la
src/Makefile.in:libptrace_la_LIBADD = ../lib/libgnu.la
src/Makefile.am:libptrace_la_LIBADD = ../lib/libgnu.la
src/Makefile:libptrace_la_DEPENDENCIES = ../lib/libgnu.la
src/Makefile:libptrace_la_LIBADD = ../lib/libgnu.la
我不知道如何生成 libtool 存档文件，并且 source 似乎没有任何 make 目标或脚本，否则会这样做。
关于管理员的注释：请在这个问题中添加标签“libptrace”——显然是一个非常受欢迎的话题——我不能这样做，因为我没有达到 1.5K 点数:(
针对 Mel 对 build.sh 的修改，以下是在 `make' 上生成的新错误：
