我正在尝试将 libcsv 转换为使用 libtool，这样我就可以在 mac os x 上使用它而不会破坏 makefile。当我尝试运行从工具生成的 makefile 时，出现以下错误：
~/software/libcsv (gnu_tools) $ make
tag=CC --mode=compile gcc -DPACKAGE_NAME=\"\" -DPACKAGE_TARNAME=\"\" -DPACKAGE_VERSION=\"\"
-DPACKAGE_STRING=\"\" -DPACKAGE_BUGREPORT=\"\" -DPACKAGE_URL=\"\" -DPACKAGE=\"libcsv\"
-DVERSION=\"3.0.1\" -I. -g -O2 -MT libcsv.lo -MD -MP -MF .deps/libcsv.Tpo -c -o libcsv.lo
libcsv.c
/bin/sh: --mode=compile: command not found
make: [libcsv.lo] Error 127 (ignored)
mv -f .deps/libcsv.Tpo .deps/libcsv.Plo
mv: rename .deps/libcsv.Tpo to .deps/libcsv.Plo: No such file or directory
make: *** [libcsv.lo] Error 1
我正在运行 OS X 10.5。因此，经过一番搜寻后，我注意到生成的 makefile 有一个空的 libtool var：
<generated makefile>
LD =
LDFLAGS =
LIBOBJS =
LIBS =
LIBTOOL =
LIPO =
LN_S =
LTLIBOBJS =
<more generated makefile>
如果我将 LIBTOOL 设置为 libtool，那么一切都很好。我假设我在下面的 autoconf 或 automake 文件中犯了一个错误：
Makefile.am
lib_LTLIBRARIES = libcsv.la
libcsv_la_SOURCES = libcsv.c
include_HEADERS = csv.h
libcsv_la_LDFLAGS = -version-info 3:1:0
ACLOCAL_AMFLAGS = -I m4
configure.ac
dn1 Process this file with autoconf to produce a configure script.
AC_INIT(libcsv.c)
AM_INIT_AUTOMAKE(libcsv, 3.0.1)
AC_PROG_CC
AC_OUTPUT(Makefile)
AC_PROG_LIBTOOL
AC_CONFIG_MACRO_DIR([m4])
AC_CHECK_FUNCS([strerror])
AC_FUNC_MALLOC
C_PROG_RANLIB
AC_PROG_CXX
LT_INIT
LT_OUTPUT
AC_TYPE_SIZE_T
如果有任何帮助，这里是 config.log 的一部分：

那么有谁知道我做错了什么？
提前致谢。
