打包命名的问题

```
tar zcvf lib-iperf3.tar.gz lib-iperf3
```

例如，

```
# tar zcvf lib-iperf3.tar.gz lib-iperf3
lib-iperf3/
lib-iperf3/main.c
lib-iperf3/patches/
lib-iperf3/patches/0001-patch-for-unikernel.patch
lib-iperf3/Makefile.uk
lib-iperf3/Config.uk
lib-iperf3/include/
lib-iperf3/include/iperf_config.h
```

```
# scp lib-iperf3.tar.gz wanghui@10.10.131.3:~/images/
```


lib-iperf3的定义是在

/root/.local/share/kraftkit/manifests/libs/iperf3.yaml

```
  1 channels:
  2 - name: staging
  3   resource: http://10.10.131.3/images/lib-iperf3.tar.gz
  4 description: Unikraft port of iperf3
  5 name: iperf3
  6 origin: http://10.10.131.3/images/iperf3.yaml
  7 provider: manifest
  8 type: lib
```



build阶段将lib-iperf3解压之后，放在了

/home/wanghui/Projects/kraft-test/my-unikernel/apps/app-iperf3/.unikraft/libs/iperf3/

app源码本身是Makefile.uk中定义，例如

```
 10 LIBIPERF3_VERSION = staging
 11 LIBIPERF3_BASENAME = iperf3-$(LIBIPERF3_VERSION)
 12 LIBIPERF3_URL=http://10.10.131.3/images/$(LIBIPERF3_BASENAME).tar.gz
 13 LIBIPERF3_PATCHDIR = $(LIBIPERF3_BASE)/patches
 14 $(eval $(call fetch,libiperf3,$(LIBIPERF3_URL)))
 15 $(eval $(call patch,libiperf3,$(LIBIPERF3_PATCHDIR),iperf3-$(LIBIPERF3_VERSION)))
```

所以ipef3本身的源码要打包之后反正该指定的位置上，例如

```
# tar zcvf iperf3-staging.tar.gz iperf3-staging
# scp  iperf3-staging.tar.gz  wanghui@10.10.131.3:~/images/
```

大致过程， kraft build，解压

```
/home/wanghui/Projects/kraft-test/my-unikernel/apps/app-iperf3/build/libiperf3/iperf3-staging.tar.gz
```

kraft build然后打patch。例如

```
patch -sd \
 /home/wanghui/Projects/kraft-test/my-unikernel/apps/app-iperf3/build/libiperf3/origin/iperf3-staging/ \
 -p1 < \
 /home/wanghui/Projects/kraft-test/my-unikernel/apps/app-iperf3/.unikraft/libs/iperf3/patches/0001-patch-for-unikernel.patch
```

如果有调整，建议删除缓存，例如

```
/root/.local/share/kraftkit/sources/libs/iperf3-staging.tar.gz
```
