SCons:GCC 忽略 -c
我正在使用基于 MinGW 的 GCC 交叉编译器来编译一个使用 SCons 作为构建系统的项目。
Python 是原生 2.6.2 版本,不是专门为 MinGW(或 Cygwin)编译的。
但是,我遇到了构建问题:
F:/pedigree/compilers/bin/i686-elf-gcc -o build\src\user\applications\apptest\ma
in.obj -c -std=gnu99 -march=i486 -fno-builtin -m32 -g0 -O3 -Wno-long-long -Wnest
ed-externs -Wall -Wextra -Wpointer-arith -Wcast-align -Wwrite-strings -Wno-long-
long -Wno-variadic-macros -Wno-unused -Wno-unused-variable -Wno-conversion -Wno-
format -Wno-empty-body -fno-stack-protector -DTHREADS -DDEBUGGER -DDEBUGGER_QWER
TY -DSERIAL_IS_FILE -DECHO_CONSOLE_TO_SERIAL -DKERNEL_NEEDS_ADDRESS_SPACE_SWITCH
-DADDITIONAL_CHECKS -DBITS_32 -DKERNEL_STANDALONE -DVERBOSE_LINKER -DX86 -DX86_
COMMON -DLITTLE_ENDIAN -D__UD_STANDALONE__ -DINSTALLER -Isrc\subsys\posix\includ
e -Ibuild\src\user\applications\apptest -Isrc\user\applications\apptest src\user
\applications\apptest\main.c
f:/pedigree/compilers/bin/../lib/gcc/i686-elf/4.4.1/../../../../i686-elf/bin/ld.
exe: crt0.o: No such file: No such file or directory
如果我将 -c 添加到 CFLAGS,我会得到一个名为“main.obj -c”的编译对象(obj 和 -c 之间有一个空格)那里)。
有人知道发生了什么事吗? 我能做些什么来解决这个问题吗?
I'm using a MinGW-based GCC cross-compiler to compile a project which uses SCons as its build system.
The Python is a native 2.6.2 version, not specifically compiled for MinGW (or Cygwin).
However, I am running into a problem with the build:
F:/pedigree/compilers/bin/i686-elf-gcc -o build\src\user\applications\apptest\ma
in.obj -c -std=gnu99 -march=i486 -fno-builtin -m32 -g0 -O3 -Wno-long-long -Wnest
ed-externs -Wall -Wextra -Wpointer-arith -Wcast-align -Wwrite-strings -Wno-long-
long -Wno-variadic-macros -Wno-unused -Wno-unused-variable -Wno-conversion -Wno-
format -Wno-empty-body -fno-stack-protector -DTHREADS -DDEBUGGER -DDEBUGGER_QWER
TY -DSERIAL_IS_FILE -DECHO_CONSOLE_TO_SERIAL -DKERNEL_NEEDS_ADDRESS_SPACE_SWITCH
-DADDITIONAL_CHECKS -DBITS_32 -DKERNEL_STANDALONE -DVERBOSE_LINKER -DX86 -DX86_
COMMON -DLITTLE_ENDIAN -D__UD_STANDALONE__ -DINSTALLER -Isrc\subsys\posix\includ
e -Ibuild\src\user\applications\apptest -Isrc\user\applications\apptest src\user
\applications\apptest\main.c
f:/pedigree/compilers/bin/../lib/gcc/i686-elf/4.4.1/../../../../i686-elf/bin/ld.
exe: crt0.o: No such file: No such file or directory
If I add -c to the CFLAGS, I get a compiled object called "main.obj -c" (there's a space between obj and -c there).
Does anyone have any idea what's happening? Is there anything I can do to solve this?

该项目使用 POSIX 平台来强制执行程序和目标文件扩展名,但是 SCons 中的 POSIX 平台定义了一个函数“转义”:
当它转义反斜杠时,会对 Windows 环境造成严重破坏。 更改为中立平台并明确指定扩展可以解决该问题。
The project uses the POSIX platform to enforce progarm and object file extensions, however the POSIX platform in SCons defines a function "escape":
When it escapes the backslashes, it wreaks havoc in the Windows environment. Changing to a neutral platform, and specifying the extensions explicitly, fixes the problem.
