GNU make yield“命令在第一个目标之前开始”错误 [英] GNU make yields “commands commence before first target” error

问题描述

尝试从Fedora 15 x86_64上的源安装Emacs 22.3。

Trying to install Emacs 22.3 from sources on Fedora 15 x86_64.

./configure

命令正常，但

使收益率错误：

[sigrlami@server emacs-22.3]# make
cd lib-src; make all  \
CC='gcc' CFLAGS='-g -O2 -Wno-pointer-sign ' CPPFLAGS='-D_BSD_SOURCE  ' \
LDFLAGS='-Wl,-znocombreloc ' MAKE='make'
make[1]: Entering directory `/home/sigrlami/bin/emacs-22.3/lib-src'
Makefile:148: *** recipe commences before first target.  Stop.
make[1]: Leaving directory `/home/sigrlami/bin/emacs-22.3/lib-src'
make: *** [lib-src] Error 2

在makefile中，我没有触摸任何东西，一切似乎都在第148行：

In makefile, where I don't touch anything, everything seems ok in row 148:

144 # ========================== start of cpp stuff =======================
145 LIBS_MOVE=$(KRB4LIB) $(DESLIB) $(KRB5LIB) $(CRYPTOLIB) $(COM_ERRLIB) $(HESIODLIB)
146 LOADLIBES= -lc
147 ALL_CFLAGS = -D_BSD_SOURCE -DHAVE_CONFIG_H
148           -I. -I../src -I${srcdir} -I${srcdir}/../src ${LDFLAGS} ${CPPFLAGS} ${CFLAGS}
149 LINK_CFLAGS = -D_BSD_SOURCE -DHAVE_CONFIG_H

有什么建议如何解决这个问题？可能系统没有一些库？

Any suggestions how to fix this? Maybe system doesn't have some libraries?

推荐答案

make输入语言是白色空间敏感的。

The make input language is white-space sensitive.

特定的命令（为了重新制作目标而要运行的动作）从一个选项卡开始，所以这个错误明确地告诉你，你的标签不合适。

In particular commands (actions to be run in order to remake targets) begin with a tab, so the error is telling you unambiguously that you have a tab out of place.

尽管只有具有特殊意义的行开头的选项卡，我尝试不使用makefile中的任何标签，而不是信号开始的命令。

While it is only tabs at the beginning of lines that have the special significance, I try to not use any tabs in my makefiles other than that the signal the beginning of commands.
