如果我不包含<lapacke.h>
,我会收到以下错误:
test.cpp:20:23: error: ‘LAPACK_ROW_MAJOR’ was not declared in this scope
LAPACKE_dsyev(LAPACK_ROW_MAJOR, jobz, uplo, N, &a[0], lda, &work[0]);
^
test.cpp:20:76: error: ‘LAPACKE_dsyev’ was not declared in this scope
LAPACKE_dsyev(LAPACK_ROW_MAJOR, jobz, uplo, N, &a[0], lda, &work[0]);
但是,当我加入<lapacke.h>
时,我会得到一长串与boost
冲突的错误。我认为这与包含<boost/algorithm/string.hpp>
有关,因为这是我正在使用的唯一boost
项目。
与lapacke
和boost
存在已知冲突吗?当我遗漏<boost/algorithm/string.hpp>
时,它编译得很好,但更广泛的代码依赖于包含。
此问题的最低示例如下:
test.h:
#include <lapacke.h>
#include <boost/algorithm/string.hpp>
#include <vector>
TEST.CPP:
#include "test.h"
void eig( std::vector< double > A, std::vector< double >& evecs, std::vector< double >&evals ) {
int N = (int)A.size();
if( N == 6 ) {
/// A is a 3x3 symmetric tensor
char jobz = 'V';
char uplo = 'L';
int N = 3;
int lda = 3;
int lwork = 15;
double work[lwork];
double a[9] = {
A[0], A[3], A[4],
A[3], A[1], A[5],
A[4], A[5], A[2]
};
LAPACKE_dsyev(LAPACK_ROW_MAJOR, jobz, uplo, N, &a[0], lda, &work[0]);
evals[0] = work[0];
evals[1] = work[1];
evals[2] = work[2];
for(int i = 0; i < 9; i++) {
evecs[i] = a[i];
}
} else {
fprintf(stderr, "ERROR: Unknown size of A in eig\n");
}
}
int main(int argc, char** argv) {
return 0;
}
生成文件:
all: test.exe
CC=g++ -std=c++11
OPTS= -O3 -Wall
LIBS= -lm -L/usr/lib/lapack -llapacke -llapack -lblas -lcblas
test.exe: $(OBJS) test.cpp
$(CC) $(OBJS) $(DEFS) $(OPTS) test.cpp -o test.exe $(LIBS)
clean:
rm -rf *.o
答案 0 :(得分:0)
似乎这可能对包含订单很敏感。首先尝试包括boost库:
#include <boost/algorithm/string.hpp>
#include <lapacke.h>
#include <vector>
对我来说,它在这个配置中编译并运行(但如果首先包含lapacke,则无法编译)。
