我现在的makefile有一些问题。我有一个cpp文件和一个h文件。我正在尝试使用c++11标准进行编译。这是我的makefile:
OBJECTS = main.o
#List all object files here separated by a space
HEADERS = main.h
#List all header files here seperated by a space
lab8: $(OBJECTS)
g++ $^ -o program3
%.o: %.cpp $(HEADERS)
g++ -std=c+
在编译C++项目时,
我犯了个错误:
/usr/lib/gcc/i686-linux-gnu/4.7/../../../i386-linux-gnu/crt1.o: In function `_start':
(.text+0xc): undefined reference to `__libc_csu_fini'
/usr/lib/gcc/i686-linux-gnu/4.7/../../../i386-linux-gnu/crt1.o: In function `_start':

为目标x86_64-unknown-linux-musl编译时会出现错误。
我就是这样做的:
cargo new foo
cd foo
rustup target add x86_64-unknown-linux-musl
cargo build --target x86_64-unknown-linux-musl
我得到了:

我安装了oneAPI工具,并试图编译示例项目vector-add。
make all
dpcpp -O2 -g -std=c++17 -o vector-add-buffers src/vector-add-buffers.cpp

I would like to find out the memory consumed by particular function in linux.
如何找出进程(C程序)中function_net()的确切内存使用情况?
在linux中有没有什么系统调用可以找到相同的结果?
For example:
/* How to find out the memory usage of this function */
**void function_net()
{
int *a = (int *)malloc(200);
}**
#include<stdio.h>
我已经在Ubuntu-14.0.0中安装了枕头,没有任何虚拟any。但是,当我试图再次在虚拟环境中安装它时,它会失败,并出现以下错误。

我正在Ubuntu14.04.5上构建一个动态库,这取决于一些静态库(Boost和OpenSSL)。
如果我在另一台Ubuntu机器上的项目中使用这个库,它将完美地工作。但是,如果我构建它并在一个拱形机器(Antergos)上的项目中使用它,那么在构建过程中它会这样说:
main.cpp.o: In function `init()':
main.cpp:(.text+0xf8): undefined reference to `Util::generateString[abi:cxx11](int)'
我正在用以下方法构建我的项目:
