在使用autotools編譯的項目上運行valgrind輸出多個堆摘要

Question

我正在使用automake編譯項目，但試圖在生成的可執行文件上運行valgrind時，它不像預期的那樣運行，似乎在實際執行之前運行8次代碼，我要檢查，併爲這段代碼堆總結根本不顯示：

以前，有一個標準的makefile編譯時有沒有這樣的問題，的valgrind將顯示正是我所期望。我使用的編譯目錄makefile.am看起來是這樣的：

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 

是這個問題事做與automake的編譯文件的方式？如果是這樣，我在makefile中做錯了什麼？

Answer 1

由於launcher正在使用libtool庫，因此構建目錄中的文件只是一個shell腳本，用於設置運行真實二進制文件所需的環境變量（通常隱藏在.libs/中）。在該腳本上運行valgrind將調試執行腳本的shell，而不是真正的二進制文件。

對一個libtool的二進制執行像valgrind或gdb任何命令正確的方法是通過libtool命令：

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

你甚至可以縮寫它爲：

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

這無論工作如何編譯launcher。
