[問題] VS2010用Matlab的shared library
我不知道VS2010環境設置有什麼問題
我試著跑Matlab提供的一個shared library的範例
用Matlab產生了libmatrix.dll, libmatrix.lib, libmatrix.h
在主程式.cpp中要使用libmatrix.dll
libmatrix.h中include了mclmcrrt.h(matlab提供)
mclmcrrt.h中又include了很多其他headfile(matlab提供)
我也在VC++ directories中增加了matlab存放所有inlcude和lib的folder
但我debugs時出現
Error 1 error C2065: 'mwArray' : undeclared
identifier c:\users\jean\documents\my
dropbox\research\code\spde_test_c\matrixdriver\matrixdriver\matrixdriver.cpp 43 1 matrixdriver
等一系列Errro
mwArray是定義在mclmcrrt.h裡所include的matrix.h
我不懂為什麼他可以順利採用mclmcrrt.h內定義的變數
卻無法採用同資料夾內的其他.h檔定義的變數
