snapcraft.yaml 看起来像这样：
name: foo
base: core18 # the base snap is the execution environment for this snap
version: '0.3.1.0' # just for humans, typically '1.2+git' or '1.3.2'
summary: bar
description: |
baz
grade: devel # must be 'stable' to release into candidate/stable channels
confinement: strict
apps:
foo:
command: bin/foo
parts:
foo:
plugin: dump
source: ./staging
stage-packages:
- mono-complete
我是这样创建快照的：
./configure.sh --prefix=./staging
make
make install
snapcraft
我试图通过将与 libc 相关的包捆绑到 snap 中来解决这个问题，并将它们添加到 stage-packages:
stage-packages:
- mono-complete
- libc6
- libc6-dev
- libc-dev-bin
- libc-bin
但问题依然存在。如果我尝试用布局映射这些：
layout:
/lib/x86_64-linux-gnu:
bind: $SNAP/lib/x86_64-linux-gnu
/usr/lib:
bind: $SNAP/usr/lib
然后我崩溃了：
$ snap run foo
execv failed: No such file or directory
也许 /usr/lib 映射太多了，但如果我将其限制为：
layout:
/lib/x86_64-linux-gnu:
bind: $SNAP/lib/x86_64-linux-gnu
/usr/lib/x86_64-linux-gnu:
bind: $SNAP/usr/lib/x86_64-linux-gnu
然后我仍然得到 DllNotFoundException。
我终于通过这个提交解决了这个问题：
https://github.com/nblockchain/geewallet/commit/cba6abf52eaf2709b8b6a974079ac5713fd3aeec
最重要的一点是将它放在您应用的启动器脚本中：
if [[ $SNAP ]]; then
PKG_DIR=$SNAP/usr
尝试将单声道应用程序捆绑到 snap 包中时，当应用程序尝试发出简单的 HTTP 请求时出现此异常：

snapcraft.yaml 看起来像这样：
name: foo
base: core18 # the base snap is the execution environment for this snap
version: '0.3.1.0' # just for humans, typically '1.2+git' or '1.3.2'
summary: bar
description: |
baz
grade: devel # must be 'stable' to release into candidate/stable channels
confinement: strict
apps:
foo:
command: bin/foo
parts:
foo:
plugin: dump
source: ./staging
stage-packages:
- mono-complete
我是这样创建快照的：
./configure.sh --prefix=./staging
make
make install
snapcraft
我试图通过将与 libc 相关的包捆绑到 snap 中来解决这个问题，并将它们添加到 stage-packages:
stage-packages:
- mono-complete
- libc6
- libc6-dev
- libc-dev-bin
- libc-bin
但问题依然存在。如果我尝试用布局映射这些：
layout:
/lib/x86_64-linux-gnu:
bind: $SNAP/lib/x86_64-linux-gnu
/usr/lib:
bind: $SNAP/usr/lib
然后我崩溃了：
$ snap run foo
execv failed: No such file or directory
也许 /usr/lib 映射太多了，但如果我将其限制为：
layout:
/lib/x86_64-linux-gnu:
bind: $SNAP/lib/x86_64-linux-gnu
/usr/lib/x86_64-linux-gnu:
bind: $SNAP/usr/lib/x86_64-linux-gnu
然后我仍然得到 DllNotFoundException。
我终于通过这个提交解决了这个问题：

最重要的一点是将它放在您应用的启动器脚本中：
if [[ $SNAP ]]; then
PKG_DIR=$SNAP/usr
