Re: FPC 3.3.1 Compiler Error Syncommons

I don't know what mORMot SVN 9577 means, since it it available on Git and Fossil only.
Current mORMot revision is 1.18.6089.

cmp r8,-8

is a perfectly valid instruction.

So this seems to be a bug of the FPC trunk.

Please use the recommended FPC 3.2 revision.

Please note this repository : https://github.com/synopse/mORMot

Code is checked out  using https://github.com/synopse/mORMot.git/trunk and TortoiseSVN giving 9577 as revision.

I'll try FPC 3.2.

Best regards.

Re: FPC 3.3.1 Compiler Error Syncommons

Tortoise SVN is for SVN, not for git.... and there is no revision in git, just a SHA hash of any commit.
So Tortoise is creating a fake revision. Don't use this number, which doesn't mean anything (there is 7203 git commits in fact).

The mORMot revision is stored in https://github.com/synopse/mORMot/blob/ … Commit.inc

Please not that the problem persisted with:
Lazarus: 2.0.10
FPC: 3.2.0

SynCommons.pas(24977,17) Error: Unknown identifier "R8D"

Re: FPC 3.3.1 Compiler Error Syncommons

There is clearly something wrong with your setup.
I don't have any problem with Lazarus 2.0.10 and FPC 3.2.0.
