That works thanks. I changed copy_built_lua to create the liblua52.a link instead of the dylib files.

Thanks. I made it default to nogui on OSX, and changed the lua lib link to be the same as linux.

In chdkptp r924, I added some commands to the devutil module for working with non-CHDK PTP operations.

In particular, dptpsendobj allows uploading files to a camera without CHDK installed, which may save some round trips with the card reader while porting.

Note that some cameras crash if the upload file name does not include A/, while other crash if it does. I don't know which are which. A540 requires A/, while IIRC all my other cameras do not.

devutil can be loaded with

Code: [Select]

 
!require'extras/devutil'.init_cli()

which can be included in your user.chdkptp startup file.

devutil has a number of other goodies, which aren't new but may not have been described here

dromlog downloads the romlog, automatically decodes vxworks
The dprop* commands allow you to snapshot and compare propcase values
dl* allow you start and stop UART redirect logging (on cameras that support it), and download the UART and camera logs

Hi all, I'm just getting started with chdkptp on OSX. I've tried running

Code: [Select]

chdkptp -elist and

Code: [Select]

./chdkptp.sh -elist but I keep getting the following output:

open_camera_dev_usb: ptp_opensession failed 0x2ff
Device status OK
open_camera_dev_usb: ptp_opensession 2 failed: 0x2ff
!1: b=020 d=028 ERROR: connection failed

Is that normal? I suspect something is trying to access the USB port. Is there a fix to this? I'm on 10.13.6.

EDIT: Solved! I forgot to run

Code: [Select]

sudo chmod -x "/System/Library/Image Capture/Devices/PTPCamera.app/Contents/MacOS/PTPCamera"

The build system with msys2 that I set up to build CHDKPTP which works fine on 874 which was then current fails on 925. The error I get is undefined reference to "clock_gettime" and to "clock_getres". Stackoverflow suggests to add -lrt to the end of the gcc call to fix that on earlier versions of gcc but I did not figure out how to do just that in the makefile.

gcc --version reports 4.8.2

Code: [Select]
gcc -Wall filename.c -lrt -O2For gcc version 4.6.1, -lrt must be after filename.c otherwise you get a link error.

Try adding adding rt to SYS_LIBS, like

Code: [Select]

SYS_LIBS=ws2_32 kernel32 winmm rt

But the stack overflow you linked in is for linux, so this may not be the solution on windows. My environment does not have an 'rt' lib. mingw targets would generally be expected to use microsoft runtime libraries.

chdkptp won't try to use clock_* if CLOCK_MONOTONIC is not defined, so you could undefine that, I guess.

That's great because it means it works. If I recall right I had trouble with putting the extlibs folder together so that it would work on current gcc, the error I was getting which I forgot but could probably reproduce by trying again with what I have suggested that I needed to use the same version of gcc as the iup and/or lua files had been compiled with and gcc 4.8 worked so I didn't try to do more. Would you zip your extlibs folder that works with gcc 9.2 and throw it on some file host? I'd then conveniently set up a current mingw instead of a legacy one...

setup-ext-libs.sh should work in an msys2 mingw shell. At the very least, -pretend should give you the download links for the CD and IUP files. It currently uses the mingw6 files.

So, there is an automatism I missed or neglected to look for. Good to know.
I put it together manually. I'll try the script with current mingw. I'll also try undefining what you pointed out.

Setting it up manually was the recommended way before the last release
The script is misc/setup-ext-libs.bash
Use -help for options.

CLOCK_MONOTONIC comes from the msys/mingw headers, so one would expect the functions to be available in the runtime libraries if defined. Undefining it would be a last resort.

What a relief, I thought I had missed that it was easy to do. Well, thanks for making it easy.
For anyone doing this later This Msys2 / MinGW writeup seems worthwhile, details building a lot of other interesting stuff on Windows as well. Once the basic steps are through get CHDKPTP trunk, run reyalps great new script misc/setup-ext-libs.bash and build CHDKPTP with make.
