我正在使用 automake 编译一个项目,但是当尝试在生成的可执行文件上运行 valgrind 时,它的行为不像预期的那样,在实际执行我要检查的代码之前运行了 8 次,以及该部分的堆摘要的代码根本不显示:

[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?
