What is does is build an example application ( simply "hello world" ) on the windows machine, transfer it to the raspberry PI and run/debug it using a GDB server on the Pi and a GDB client from Vscode on the windows machine.
Now I would like to try and expand that a bit to develop a GUI based application in the same way.
I have done some checking and I think that using the GTK-2.0 library is probably the way to go. On the PI I have installed that library successfully but now I would like to transfer it to the appropriate location in the msys32 directory where the cross compilation tools are located as well. The problem is that it is not entirely clear to me where all the header and library files are located on the PI. Running pkg-config --cflags --libs gtk+-2.0 does tell me what I should add as extra includes when I run the gcc build tool on the PI but it is not clear how and where I could copy the required header and library files so that the cross compilation tool on the windows machine could find them.
Any suggestions/ideas would be very much appreciated.
Edit: added "directory' to indicate that the mentioned msys32 is a directory.
Thanks. I have recently done an application like that: a VB.NET application developed/built on a Windows 10 machine and then executed on the Raspberry PI using mono. It worked well but I am now investigating if there is a more native way to do it.
I have found some interesting info in a document called "An introduction to C&GUI programming" by Simon Long, one of the engineers who works for the Raspberry PI Foundation.
Unfortunately everything in it is built on the Raspberry PI itself via command line etc... and I really like to use my VScode IDE on my Windows machine .
If I don't succeed I will revert to Visual studio, C#.NET and mono on the PI but I will keep looking for a while.
The remote development option for VScode does work very neatly. Edit/develop everything from Visual studio code on the windows 10 machine, build and test everything on the Raspberry PI. It takes a bit of doing to get it all to work nicely together but I have a working application that uses the GTK-2.0 library that is installed on the PI. Thanks for the suggestion.
One of the most beautiful pieces of kit ever built, I think. Second would be the LNER Class A4, which has held the speed record for steam engines at 126 MPH since 1938! Maybe I should change my name to Mallard, instead?
I have dual citizenship. Born in the UK, but we emigrated to Canada when I was only six, which was over 50 years ago, now. So, yeah, I do, bit it's somewhat tenuous. I don't really remember much about life in Britain.
i set up python 3.4 and PostgreSQL 10.6 on Oracle Linux 7.4.
when i create plpython3u it's error.
could not load library "/u01/PostgreSQL/10/lib/postgresql/plpython3.so": libpython3.4m.so.1.0: cannot open shared object file: No such file or directory
then i add export LD_LIBRARY_PATH=/usr/local/lib:$LD_LIBRARY_PATH in file ~/bash_profile
Finally, i have to restart services postgreSQL : pg_ctl restart ==> it's ok.
but when i reboot linux , it will be error again, i guess LD_LIBRARY_PATH load after service postgres start. How i Can resolve it ?
Thank you !
There should be some information in the PostgreSQL installation guide as to how to set this up. But if not then I would guess it needs to be set in one of the /etc/rc startup scripts. You will need to check the Linux man pages to decide which one you should use.
to /lib/systemd/system/postgresql.service. The best place for that would be right after the line that says Export=PGDATA=path-to-pgdata
Meanwhile, I would follow Richard's advice and contact the PostgreSQL mailing list and ask there. They may have a better solution so that when you update to PGSQL 10.XX or 11.XX, you won't have to continually remember to edit the startup script.
I am new to Linux Shell (there is #!/bin/sh in the beginning of my file) and I need to write a Git pre-commit hook, for my Visual Studio C# Project repository, that must prevent a commit from being performed if a specific file
Thank you. The hooks are already enabled and working and they are calling standard .bat-files as it is now. My plan was to write as much as possible in standard .bat-files, but I think a check like this is difficult to pass on to a .bat-file.

is not part of the selected files to be committed
What exactly do you mean by this? Does the file need to be added, modified or anyway altered in the commit, or just to make sure that it is not deleted?
I use TortoiseGit and when I click commit I get a list of all files with modifications. Next to each file name in the list there's a checkbox that I can mark the specific file for inclusion in the commit about to happen. So, the user must always check the checkbox next to GitCommitDateAndTime.cs. Now, you could argue that I could always programmatically click the checkbox as a convenience for the user, but I have seen that some of my colleagues use git from some kind of command line tool so this solution wouldn't work for them.
If I was able to pass parameters (in this case ASCII-strings with files that have their checkboxes checked) to an .exe-file then this problem would be gone since it would be extremely easy to write a C#-application that would perform the check, but I have no clue how to do that either.
I have not heard of such things in Linux. Are you using the wrong terminology, or the wrong files?
No, not in Linux, in Windows (the type of .bat-files you could run on dos in the 1990's). So in this case I start off with a Git hook file written in #!/bin/sh, which I believe has some relation with Linux, but since I have no knowledge of that I want to move into Windows environment (.bat-file or .exe written in C#), but I have no idea how to make that bridge and pass parameters.
