[Program output appears here, nothing appears afterwards]  

以前,当使用标准 makefile 进行编译时,没有此类问题,valgrind 会完全显示我的预期。makefile.am我用于编译目录的内容如下所示:

lib_LTLIBRARIES = libfile_util.la libmath_util.la libgeneral_util.la libparamlist.la
libfile_util_la_SOURCES = file_util.c file_util.h
libmath_util_la_SOURCES = math_util.c math_util.h
libgeneral_util_la_SOURCES = general_util.c general_util.h
libparamlist_la_SOURCES = paramlist.c paramlist.h

bin_PROGRAMS = launcher
generator_CFLAGS = -I/usr/include/muParser
generator_SOURCES = generator.c generator.h
estimator_SOURCES = estimator.c estimator.h
estimator_iwls_SOURCES = estimator_IWLS.c estimator.h
estimator_piecewise_SOURCES = estimator_IWLS.c estimator_piecewise.c estimator.h
estimator_baseline_SOURCES = estimator_IWLS.c estimator_piecewise.c estimator_baseline.c estimator.h
launcher_CFLAGS = -I/usr/include/muParser
launcher_SOURCES = launcher.c generator.c estimator.c estimator.h generator.h
generator_LDADD = libfile_util.la libmath_util.la libgeneral_util.la libparamlist.la
launcher_LDADD = libfile_util.la libmath_util.la libgeneral_util.la libparamlist.la
estimator_iwls_LDADD = libfile_util.la libmath_util.la libgeneral_util.la libparamlist.la
estimator_piecewise_LDADD = libfile_util.la libmath_util.la libgeneral_util.la libparamlist.la
estimator_baseline_LDADD = libfile_util.la libmath_util.la libgeneral_util.la libparamlist.la

这个问题与 automake 编译文件的方式有关吗?如果是这样,我在makefile中做错了什么?

因为launcher使用的是 libtool 库,所以构建目录中的文件只是一个 shell 脚本,它设置必要的环境变量来运行真正的二进制文件(通常隐藏在.libs/. 在该脚本上运行 valgrind 将调试执行脚本的 shell,而不是您真正的二进制文件。

在 libtool 二进制文件中执行任何命令的正确方法valgrindgdb通过以下libtool命令:

libtool --mode=execute valgrind ./launcher -g ../data/params.txt

您甚至可以将其缩写为:

libtool e valgrind ./launcher -g ../data/params.txt

无论如何launcher编译,这都将起作用。
