5 | Introduction |
---|

---|

---|
8 | Building an rpm requires to have a tar archive of the sources, and a |
---|
9 | rpm-spec files specifying the details of building. |
---|
10 | |
---|
11 | To support per bsp rpms, one rpm-spec is used per BSP. |
---|
12 | Instead of writing one rpm-spec for each BSP, I have written a shell script |
---|
13 | (mkspec) which generates one *.spec (rtems-<target_alias>-<bsp>.spec) per BSP |
---|
14 | bsp from an rpm-spec template (rtems.spec.in). |
---|
15 | |
---|
16 | A second shell script (mkrpms) is a convienience script which invokes a |
---|
17 | sequence of building rpms for several bsps. |
---|
18 | |
---|
19 | |
---|
20 | mkbinutilspec |
---|
21 | ------------- |
---|
22 | |
---|
23 | mkbinutilspec takes two arguments: |
---|
24 | |
---|
25 | $1 ... the target_alias for binutils RPMs of this toolset |
---|
26 | |
---|
27 | Invoking mkbinutilspec will generate a <target_alias>-binutils.spec either in |
---|
28 | |
---|
29 | /usr/src/packages/SPECS (SuSE convention) or |
---|
30 | /usr/src/redhat/SPECS (Redhat convention) or |
---|
31 | /usr/src/SPECS |
---|
32 | |
---|
33 | Eg. ./mkbinutilspec sparc-rtems generates |
---|
34 | |
---|
35 | On SuSE-6.2: /usr/src/packages/SPECS/sparc-rtems-binutils.spec |
---|
36 | On RedHat 6.0: /usr/src/redhat/SPECS/sparc-rtems-binutils.spec |
---|
37 | |
---|
38 | mkgccnewlibspec |
---|
39 | --------------- |
---|
40 | |
---|
41 | mkgccnewlibspec takes two arguments: |
---|
42 | |
---|
43 | $1 ... the target_alias for the gcc/newlib RPMs of this toolset |
---|
44 | |
---|
45 | Invoking mkgccnewlibspec will generate a <target_alias>-gccnewlibs.spec |
---|
46 | either in: |
---|
47 | |
---|
48 | /usr/src/packages/SPECS (SuSE convention) or |
---|
49 | /usr/src/redhat/SPECS (Redhat convention) or |
---|
50 | /usr/src/SPECS |
---|
51 | |
---|
52 | Eg. ./mkgccnewlibspec sparc-rtems generates |
---|
53 | |
---|
54 | On SuSE-6.2: /usr/src/packages/SPECS/sparc-rtems-gcc_newlib.spec |
---|
55 | On RedHat 6.0: /usr/src/redhat/SPECS/sparc-rtems-gcc_newlib.spec |
---|
56 | |
---|
57 | mkgdbspec |
---|
58 | --------- |
---|
59 | |
---|
60 | mkgdbspec takes two arguments: |
---|
61 | |
---|
62 | $1 ... the target_alias for the gdb RPMs of this toolset |
---|
63 | |
---|
64 | Invoking mkgdbspec will generate a <target_alias>-gdb.spec |
---|
65 | either in: |
---|
66 | |
---|
67 | /usr/src/packages/SPECS (SuSE convention) or |
---|
68 | /usr/src/redhat/SPECS (Redhat convention) or |
---|
69 | /usr/src/SPECS |
---|
70 | |
---|
71 | Eg. ./mkgdbspec sparc-rtems generates |
---|
72 | |
---|
73 | On SuSE-6.2: /usr/src/packages/SPECS/sparc-rtems-gcc_newlib.spec |
---|
74 | On RedHat 6.0: /usr/src/redhat/SPECS/sparc-rtems-gcc_newlib.spec |

79 | # mkbspspec |
---|
80 | # --------- |

81 | # |
---|
82 | # mkbspspec takes two arguments: |

83 | # $1 ... the target_alias this bsp belongs to |
---|
84 | # $2 ... the bsp to be built |
---|
85 | # |
---|
86 | # Invoking mkbspspec will generate a rtems-<target_alias>-<bsp>.spec either in |

93 | |
---|
94 | mkspec |

---|
100 | $2 ... the bsp to be built |
---|
101 | |
---|
102 | Invoking mkspec will generate a set of spec files either in: |
---|
103 | |
---|
104 | /usr/src/packages/SPECS (SuSE convention) or |

202 | Known Bugs/Deficiencies |
---|
203 | ----------------------- |
---|
204 | |
---|
205 | * All files mentioned in here are in its early infancy ;-) |
---|
206 | |
---|
207 | * Building for a single bsp requires an own copy of the source tree inside |
---|
208 | rpm's build directory. |
---|
209 | * Building inside the RTEMS source tree doesn't work. |
---|
210 | * Dependencies on toolchain-rpms not yet supported in rtems.spec.in. |
---|
211 | * Installing multiple binary bsp rpms for the same target can cause |
---|
212 | warnings from rpm, because these bsp-rpms share files. |
---|
213 | * rtems.spec.in is prepared for rpm relocation support, but RTEMS is not |
---|
214 | relocatible (yet?) |
---|
215 | * rtems.spec.in deserves to be extended (description, authors etc) |
---|
216 | * The final packaging stage to build a binary rpm takes an awful lot of |
---|
217 | time - deserves to be investigated. |
---|
218 | * Some RTEMS's cross executables (eg. hello.exe for sparc-rtems/erc32) cause |
---|
219 | warnings from rpm and/or objdump. AFAIS, this is a bug in rpm. |
---|
220 | * Probably many more ... |
---|
221 | |
---|
222 | * Last but not least: RTEMS should be split. |
---|
223 | |
---|
224 | Remarks |
---|
225 | ------- |
---|
226 | * It would make sense to split RTEMS host/cross-tools and files depending on |
---|
227 | the target only (<target_alias>/make/*.cfg -- Whow, RTEMS really has files |
---|
228 | which depend on the target only :) into separate rpms. |
---|
229 | * Instead of using a single rpm-spec for each bsp, RTEMS could also use a |
---|
230 | single rpm-spec for all (or at least a given subset of all) bsps of a target. |
---|
231 | * rpm -b[b|a] leaves its built trees unpacked in |
---|
232 | /usr/src/[packages|redhat]/BUILD. Therefore you will rather soon run out of disc |
---|
233 | space if not removing them. (Use rpm --clean -b[a|b] for cleaning them up |
---|
234 | automatically after building) |
---|
235 | * The size of binary rpms can differ up to one magnitude depending on the |
---|
236 | target/bsp (eg. sh-rtems/gensh1 ~10MB vs. sh-rtemself/gensh1 ~32MB) |
