当我尝试构建我的应用程序时，出现链接器错误undefined reference to (..)。所有未找到的函数都是从 meschach 库中导入的。我认为库已正确安装：
whereis libmeschach
libmeschach: /lib/libmeschach.so /usr/lib/libmeschach.so /lib64/libmeschach.so
我的 SCons 文件：
import os
import sys
import functools
PROJECT_ROOT = os.path.curdir
doc_path = functools.partial(os.path.join, PROJECT_ROOT, 'doc')
src_path = functools.partial(os.path.join, PROJECT_ROOT, 'src')
out_path = functools.partial(os.path.join, PROJECT_ROOT, 'build')
cpp_flags = {
'linux2' : '-Wall -Wextra -pedantic -fopenmp -O3',
'win32' : '/w /MD /openmp'
}
env = Environment(ENV=os.environ,CPPFLAGS=cpp_flags[sys.platform])
env.VariantDir(variant_dir=out_path(),src_dir=src_path())
env.Program(target=out_path('cholesky'), source=Glob(out_path('*.cpp')), LIBS=['m'])
我使用 Arch Linux 64 位。
编辑：我用 Makefile 替换了 SCons，但错误仍然存在：
CC=g++
CFLAGS=-c -Wall -Wextra -pedantic -I./externals/include
LIB=./externals/lib/meschach.a -lm
