问题描述
我如何进行这项工作?错误显示为"make:somevariable:找不到命令"
How do I make this work? It errors out with "make: somevariable: Command not found"
sometarget:
somevariable = somevalue
完整示例:
CXXFLAGS = -I/usr/include/test -shared -fPIC
OBJ = main.o Server.o
blabla : $(OBJ)
ifeq ($(argsexec),true)
# Creates an executable
CXXFLAGS = -I/usr/include/test
$(CXX) -o blabla $(OBJ) $(CXXFLAGS)
else
# Creates a library
DESTDIR = /home/pc
$(CXX) -o blabla $(OBJ) $(CXXFLAGS)
./bn.sh
endif
推荐答案
我找到了使用 eval
函数:
I found a solution using the eval
function:
$(eval variablename=whatever)
这有效:)
(尽管我现在可以尝试找到一个更简单的构建系统;))
(although I may now try to find an easier build system ;))
