我需要在我的生成文件中設置幾個標誌,這些標誌只需要特定的窗口即我不希望它們在其他操作系統上「看到」。我正在使用MinGW來構建我的項目。這些是我想要只爲窗口設置的標誌:在生成文件中添加特定於平臺的標誌
AM_LDFLAGS += -lws2_32
AM_LDFLAGS += -Xlinker --allow-multiple-definition
這是我在做makefile.am:
SYS := $(shell gcc -dumpmachine)
ifneq (, $(findstring mingw, $(SYS)))
AM_LDFLAGS += -lws2_32
AM_LDFLAGS += -Xlinker --allow-multiple-definition
endif
當我做autoreconf -isf
,它失敗,以下消息:
Makefile.am:34: endif without if
Makefile.am:30: `:='-style assignments are not portable
Makefile.am:30: shell gcc -dumpmachine: non-POSIX variable name
Makefile.am:30: (probably a GNU make extension)
Makefile.am:31: findstring mingw, $(SYS: non-POSIX variable name
Makefile.am:31: (probably a GNU make extension)
aminclude.mk:162: .PHONY was already defined in condition TRUE, which includes condition DX_COND_doc ...

/mingw/share/automake-1.11/am/distdir.am: ... overrides Automake variable `distdir' defined here

有關如何處理此問題的任何建議?
最好使用預定義的'$ host_os'將處理交叉編譯的情況 – vitalyster
@vitalyster我configure.ac嘗試這樣做:在 窗口*) AM_LDFLAGS + = -lws2_32 AM_LDFLAGS 'AC_CANONICAL_HOST 情況下$ host_os + = -Xlinker --allow-multiple-definition ;; *) AM_LDFLAGS + = AM_LDFLAGS + = ;; esac'但沒有工作。我會嘗試@ptomato的建議,看看它是否有效。 –
@ptomato我嘗試了你的建議,使乾淨;使strtok相關的錯誤失敗。 所以我編輯了makefile.am作爲'if!MINGW .....',這沒有任何意義。我在這裏錯過了什麼嗎? –
