我想在Makefile中使用PGI编译器的-U__GNUG__标志,试图编译一个文件夹内的所有.cpp文件,链接到Armadillo(使用g ++编译器中,代码编译和运行),我有Makefile文件如下:Makefile使用PGI编译器链接到Armadillo库
CC=pgc++
CFLAGS= -U__GNUG__ -std=c++11 -fast -acc -Minfo=accel -larmadillo -lgsl -w
all:
${CC} ${CFLAGS} *.cpp -o cg
clean:
rm -Rf cg pgprof* *.o core
看来,对象文件的汇编工作,但未能编译最终的可执行文件。这个Makefile有什么问题?
编译使用的代码:
~$ make
我收到以下错误:
cis.o: In function `arma::Col<double>::pod_type arma::op_norm::vec_norm_2<arma::Col<double> >(arma::Proxy<arma::Col<double> > const&, arma::arma_not_cx<arma::Col<double>::elem_type>::result const*)':

是应该由包括标志-U__GNUG__固定。
任何建议将不胜感激。
是否使用你期望它用来编译你的二进制文件的命令? (您没有在粘贴的输出中包含该文件。) –
