std:string to boost::filesystem::path, then, create directories.
Hi, all: After upgrading to boost 1.48.0, my code seems to stopping working. The original code is pretty simple: char* folderName = "./test"; if (!boost::filesystem::is_directory( folderName ) ) boost::filesystem::create_directories( folderName ); It used to work fine but after upgrading to boost 1.48.0, I got the following annoying errors always: Unhandled exception at 0x51d8ee9e (msvcr90d.dll) in myTest.exe: 0xC0000005: Access violation writing location 0xcdcdcdcd. The program stops at the line "if (!boost::filesystem::is_directory( folderName ) )", and the call stack seems to hint it's an error coming from memcpy.asm " TrailUp1: mov al,[esi] ;U - get byte from source ;V - spare mov [edi],al ;U - put byte in destination mov eax,[dst] ;V - return pointer to destination pop esi ;U - restore esi pop edi ;V - restore edi M_EXIT " Can anybody help me out? Thank you very much.... Best Regards Pei -- Pei JIA Email: jp4work@gmail.com cell: +1 604-362-5816 Welcome to Vision Open http://www.visionopen.com
Hi,
Unhandled exception at 0x51d8ee9e (msvcr90d.dll) in myTest.exe: 0xC0000005: Access violation writing location 0xcdcdcdcd.
Are you sure you use debug version of boost (as you get exception from debug version of msvcr)? I use 1.48 and is_directory on win32/win64/lin32/lin64 and I don't get any errors, also with win32 debug configurations. Regards, Bogdan

I forgot to add that I use 1.48 with filesystem v2, however I've tested 1.48 v3 on win32 (also debug version) and I didn't noticed any problems.
Hi, Bogdan: Thank you for your prompt reply.... I don't even know whether debug or release of boost 1.48.0 is under use. But, I'm pretty sure under C:\boost_1_48_0\stage\lib, I've got 2 versions of built libraries for each sub-package. For example, for regex, I've got libboost_regex-vc90-mt-1_48.lib libboost_regex-vc90-mt-gd-1_48.lib I believe when debugging, libboost_regex-vc90-mt-gd-1_48.lib is under use. My code is now as simple as, still get the error. string tests = "aaa"; const char* aaa = tests.c_str(); boost::filesystem::path p ( aaa ); BTW, when I use VS2008's command prompt to build boost 1.48.0, there is no error report at all. What can I do????? BTW, I didn't specify which boost libraries I'm using at all. It seems VS2008 automatically find boost library by itself. I don't need to specify any dependent libraries in Linker-Input .... Cheers Pei On Fri, Feb 10, 2012 at 1:56 AM, Bogdan Slusarczyk < bogdan.slusarczyk@aldec.com.pl> wrote:

Hello, Bogdan: Happen to notice if I change nothing else but only boost back to version 1.42.0, and use "boost::filesystem::path" , my project works fine. I also tested examples including "tut1, tut2, tut3, tut4" of boost 1.48.0, everything seems to work fine. However, I seriously have no idea where the conflicts come from ( I mean the conflicts between boost 1.48.0 and my code which has nothing to do with boost at all ) why there seems to be no conflicts between boost 1.42.0 and my code??? So far, the only conclusion I can draw is: filesystem3 is not stable yet. Pei On Fri, Feb 10, 2012 at 2:32 PM, JIA Pei <jp4work@gmail.com> wrote:

Most likely, this is not the reason. Check that you don't mix different boost version (eg., that you don't include some older boost headers).
