twain on linux

[avnm]

I have read that twain 2.0 is available on linux platforms.

1) I suppose it needs to be installed on linux, may i ask how to install it?
For instance on ubuntu and possibly also suse linux

2) I suppose to work with a scanner i need a linux/twain driver.
Where is a list of the available drivers?
Do i need to install the driver separately?

Thanks

Where is a list of the available drivers?

there isn’t one, nor is there one for windows or mac.

Do i need to install the driver separately?

yes.

As regard the first question, i found there is a link to the data source manager on the main page.

I am trying to install the example application on linux ubuntu.
I mean the one at this url

https://sourceforge.net/project/showfiles.php?group_id=212173 .

I followed the instructions but when i make i get this

main.cpp: In function âvoid EnableDS()â:
main.cpp:312: error: âMSGâ was not declared in this scope
main.cpp:312: error: expected `;’ before âMsgâ
main.cpp:314: error: âLPMSGâ was not declared in this scope
main.cpp:314: error: âMsgâ was not declared in this scope
main.cpp:314: error: âGetMessageâ was not declared in this scope
main.cpp:319: error: âMsgâ was not declared in this scope
main.cpp:348: error: âLPMSGâ was not declared in this scope
main.cpp:348: error: âTranslateMessageâ was not declared in this scope
main.cpp:349: error: âDispatchMessageâ was not declared in this scope
make: *** [main.o] Error 1

what’s wrong?

[gabe]

it looks to me (when reading TranslateMessage & DispatchMessage) that you’re compiling the windows source. there should have been a #define that caused the compile to only compile the *nix code. Or are TranslateMessage & DispatchMessage defined under your *nix platform?

What are you compiling with?

.

root@test-rfid:/tmp/twainapp.source.2.0.5/Twain_App_sample01/src# qmake src.pro

root@test-rfid:/tmp/twainapp.source.2.0.5/Twain_App_sample01/src# make

Yes you have discovered a bug in the code.
some #ifdef TWH_CMP_MSC around the code for MSG should resolve it for Linux for now.

#ifdef TWH_CMP_MSC

MSG Msg;



if(!GetMessage((LPMSG)&Msg, NULL, 0, 0))

{

break;//WM_QUIT

}

#endif

#ifdef TWH_CMP_MSC

TranslateMessage ((LPMSG)&Msg);

DispatchMessage ((LPMSG)&Msg);

#endif
