Building Opencpn using mingw (gcc) on Windows

[rgleason]

In the opencpn-mingw/buildwin directory there are lots of files related to NSIS all of type 2.46.3 including "nsis-2.46-Unicode-setup.exe"

What do I do about that? Those were part of the git pull!

I am going to try changing the compression type..much simpler. Just change project.nsi line.

[rgleason]

Ok,
I found out that if I right click on project.nsi I can select the type of comression etc.
Ran a couple with zlib and failed. Then I went in and edited the file and just ran it.
Took off the /Final and ran LZMA

Got this error:
ClearErrors
FileOpen: $TEMP\opencpn_hdd_full_scan.tmp as r -> $R0
IfErrors ?done1:
!insertmacro: _Do
!insertmacro: end of _Do

Error in script "C:\Data-Dart\Up-Soft\Navigation\opencpn-mingw\build\_CPack_Packages\win32\NSIS\project.nsi " on line 1909 -- aborting creation process

--So it is looking for itself and I have it open or something?

[rgleason]

Ok from right click project.nsi tried Bzip2 without Unicode
Error: FileReadUTF16LE is only available when building a Unicode installer
Error in script "C:\Data-Dart\Up-Soft\Navigation\opencpn-mingw\build\_CPack_Packages\win32\NSIS\project.nsi " on line 1909 -- aborting creation process

====
Then tried right click on project.nsi pick Bzip2 with Unicode got this error
SetCompressor: /FINAL bzip2
Processing config:
!define: "MUI_INSERT_NSISCONF"=""

Changing directory to: "C:\Data-Dart\Up-Soft\Navigation\opencpn-mingw\build\_CPack_Packages\win32\NSIS"

Processing script file: "C:\Data-Dart\Up-Soft\Navigation\opencpn-mingw\build\_CPack_Packages\win32\NSIS\project.nsi "

[rgleason]

Change project.nsi compression to Bzip2 with unicode. Then

8. Compile Installer
9. cmake -G "MSYS Makefiles" ..
10. make
11. make package
12. output now says:

CPack Error:
Problem running NSIS command:
"C:/Program Files (x86)/NSIS/Unicode.makensis.exe"
"C:/data-dart/.../opencpn-mingw/build/_Cpack_Packages/win32/NSIS/NSISoutput.log for errors.
CPack Error: Problem compressing directory.
CPack Error: Error when gnerating package: Opencpn
make: *** [package] Error 1

NSISoutput.log
Processing script file: "C:/Data-Dart/Up-Soft/Navigation/opencpn-mingw/build/_CPack_Packages/win32/NSIS/project.nsi"

Invalid command: Unicode

Error in script "C:/Data-Dart/Up-Soft/Navigation/opencpn-mingw/build/_CPack_Packages/win32/NSIS/project.nsi" on line 36 -- aborting creation process

So somehow in compiling the compression type was reset again to LZMA

--Later - It appears that "make install" is changing it back to LZMA with unicode.

REMOVED NSIS 2.46.33
REMOVED NSIS 3.0b
REINSTALLED NSIS 3.0b in NSIS directory
Reran
8. Compile Installer
9. cmake -G "MSYS Makefiles" ..
10. make
11. make package
12. output now says:

CPack - Package: C:/Data-Dart/...opencpn_3.3.1911_setup.exe generated.

Dare I try it? Should I upload it?

Thanks Sean for the advice to load nsis 3.0b you were right.

It would be interesting to compare the size of this installer to the official installer.

I tried to use llvm to compile opencpn, and it compiles and links with a small change, but when running crashes, no idea why.

[rgleason]

mingw (gcc) - opencpn_3.3.1911_setup.exe 31,538 kb
msvc++ - opencpn_3.3.1931_setup.exe 35,997 kb

I've installed to C:/MinGW with mingw-get-setup.exe
and can compile using the msys.bat file, but there is no exe for MinGW or graphical interface and I get lost in the install documentation. Is there anything more than msys.bat?


I do like the messages better with mingw, but still getting familiar.
Is there a way to copy and paste pathnames into msys? That would be helpful.
Also how do you highlight and copy parts of the output of msys?
I use these all the time with msvcc command line.

The msys.bat file is pretty big.

Also How do you do a back trace as in MSVCC graphical?
Is there a graphical interface?
--Maybe I should try debug mode and see?

I suppose this is "minimal" so some of these things aren't available?

[rgleason]

I find the Install Notes very muddy, unclear, and uncrisp with too many conditionals.

Computer > Right Click > Properties > Advanced System Settings > Environment Variables
Have now set these additional paths:

;C:\MinGW\bin;C:\MinGW\MSYS\1.0\local\bin;C:\MinGW \MSYS\1.0\bin

Following Getting Started | MinGW
See the "Environment Settings" (at bottom)

Now what exactly IS it that they want me to do with STartup? ---Why don't they just install it for heavens sake? --They need to use NSIS I think!

Installed the NSIS Install file after deleting my MSVC Opencpn v3.3.1911 and the MinGW (gcc) NSIS install went into a new Opencpn 3.3.1911 directory very nicely.

It RUNS! along with Grib and Dash. Is there a way to update this current to 1931 or do I run it this way? --I suppose I should be testing the beta when I am using Opencpn however!

Rick wrote about the MinGW notes on the MinGW website Getting Started

I was not refering to the Opencpn MinGW install notes.

I have made some changes and (hopefully) some improvements and clarifications to the Opencpn MinGW compile page that Sean created here:

Just trying to compile OpenCPN for now. Used the instructions at aforementioned web page. All seemed to go well as far as installing MinGW and other tools. But making OpenCPN hits early error (see below). Any idea what I missed?

I'm trying to compile OpenCPN 4.0 using MinGW/gcc. The 'make' step fails with an error message: 'DISPLAY_DEVICE_ACTIVE' was not in this scope. The failure occurs when compiling chart1.cpp. I haven't been able to locate the identifier in either source or include files.

Does anyone have a suggestion?

Greg...
It is used in chart1.cpp and according to https://msdn.microsoft.com/en-us/lib...=vs.85%29.aspx should be defined in wingdi.h, but looking at the MinGW sources it isn't. Try to replace it with DISPLAY_DEVICE_ATTACHED_TO_DESKTOP
Still wondering what is this effort good for...
