For personal purposes I needed to build wine on my VT310-DP board using current pkgsrc<\/a> package manager. I initially\u00a0 tried to build and install emulators\/wine package for this purpose as an “obvious” choice. It contains a build for wine-1.6.2. I face two compilation issues during the build. First build issue was complaining about undefined yywrap variable in tools\/wrc\/parser.yy.c file. \u00a0 I “fixed” it by commenting out \/\/#undef yywrap.<\/p>\n

--- tools\/wrc\/parser.yy.c 2017-08-19 15:29:22.954733511 +0300\r\n+++ tools\/wrc\/parser.yy.c 2017-08-19 15:30:39.061280133 +0300\r\n@@ -837,7 +837,7 @@\r\n #include \"newstruc.h\"\r\n \r\n #include \"parser.tab.h\"\r\n-#undef yywrap\r\n+\/\/#undef yywrap\r\n \r\n \/* Always update the current character position within a line *\/\r\n #define YY_USER_ACTION char_number+=yyleng; wanted_id = want_id; want_id = 0;\r\n\r\n<\/pre>\n
Another one was server\/ptrace.c issue. There were two code blocks using dbregs.drX variables (X is a number from 0-7), for example\u00a0 context->debug.i386_regs.dr0 = dbregs.dr0. Compiler was complaining that non of drX variables were defined in the struct. From the code I realized that it was using dbreg struct. Then I checked system’s \/usr\/include\/machine\/reg.h file, dbreg struct was defined like this:<\/p>\n
\/*\r\n * Debug Registers\r\n *\r\n * DR0-DR3 Debug Address Registers\r\n * DR4-DR5 Reserved\r\n * DR6 Debug Status Register\r\n * DR7 Debug Control Register\r\n *\/\r\nstruct dbreg {\r\n int dr[8];\r\n};<\/pre>\n
It is visible that that dbreg struct has one dr variable which is an array of int. So I replaced all the dbregs.drX lines with array indexes instead dbregs.dr[X] line. It helped and wine was build. Unfortunately running any executable was failing with an error message: “wine: failed to create the process heap”. I tried to investigate error online but it was usually pointing to some old wine bug and workaround to build a manual Linux kernel which I wasn’t sure how to apply on NetBSD. One thing that caught my eye was that NetBSD has a newer wine package called wine-devel<\/strong>. It builds wine-1.9.18. During wine-devel compilation I didn’t face parser.yy.c issue anymore but ptrace.c one was still the same. I made this modification to the file:<\/p>\n

Applying this patch fixed the build and I had a newer version of wine ready. Trying it out proved to be successful for some small Windows executable files I was planning to use. Old wine bug didn’t reoccur. So if you want to build wine on NetBSD 8.0 beta and current pkgsrc I recommend using wine-devel package and apply the patch above if build fails.<\/p>\n","protected":false},"excerpt":{"rendered":"
