Lazarus - problem with compiling

#1 Postby mariusz » Wed Nov 10, 2010 12:47 pm

Hi

I copied strategy from lesson 2, but when I am trying to compile the project I get message:

"StrategyInterfaceUnit.pas(1,1)Fatal: Can't find unit graphics used by StrategyInterfaceUnit"

Where can I get file graphics from?



also the link to video about how to compile indicator using lazarus

in "Development tools" thread on this forum leads to something completely different ...

:)

cheers

Hello,

Please do the following steps to fix this issue:

1) Go to Project -> Project Inspector menu
2) In next window click "Add"
3) In "Add to project window" choose "LCL" on "New Requirement" tab (see "LCL.gif" screenshot)
4) Go to Project -> "Compiler Options"
5) Switch to "Parsing" tab and choose "Delphi" as a Syntax mode
6) Switch to "Code" tab and choose "Target OS" = WinXX

I hope that project will be built successfully after that.

And thank you for your note about video, we'll fix it.

Hi FT Support,

Try out the Lazarus 0.9.30. Setup according to your above instruction.
But still build with error missing WS***.

Found that your youtube is using 0.9.26.2. Try it out and everything run
smoothly accordingly.

So I believed it is safe and reliable to use Lazarus 0.9.26.2, to avoid unnecessary problem for compilation.


However, found that the Lazarus compiled DLL size is huge, approx 6MB as compare to delphi 100KB.

Can you recommend some ways to reduce the size in the Lazarus Options
?

//---------------------------------------------------

Fortunately, i also found from web that you can implement lazarus tools to reduce the size tremendously by these commands:

strip -s BollingerBands.dll
upx BollingerBands.dll

My BollingerBands.dll 6M reduced to 300K and worked on FT2.


Is there any way to setup the build process to include the above reduce size commands ?
