Why does not git fully download dependent libraries throw submodule-CodePudding

My code has some dependent libraries throw submodule, I clone the codes throw two ways:

git clone --recursive ***

git submodule update --init --remote --recursive

but neither of them works, after I clone the code, the size of dependent libraries are about 130 like this

-rw-rw-r-- 1 klen klen 130 Aug 25 11:51 libaddress_sorting.a
-rw-rw-r-- 1 klen klen 131 Aug 25 11:51 libares.a
-rw-rw-r-- 1 klen klen 133 Aug 25 11:51 libboringssl.a
-rw-rw-r-- 1 klen klen 132 Aug 25 11:51 libgpr.a
-rw-rw-r-- 1 klen klen 134 Aug 25 11:51 libgrpc.a
-rw-rw-r-- 1 klen klen 133 Aug 25 11:51 libgrpc  .a
-rw-rw-r-- 1 klen klen 133 Aug 25 11:51 libgrpc_abseil.a
-rw-rw-r-- 1 klen klen 133 Aug 25 11:51 libgrpc  _alts.a
-rw-rw-r-- 1 klen klen 131 Aug 25 11:51 libgrpc_csharp_ext.a

but their real sizes are

-rw-rw-r-- 1 klen klen     46850 Aug 10 15:32 libaddress_sorting.a
-rw-rw-r-- 1 klen klen    824784 Aug 10 15:32 libares.a
-rw-rw-r-- 1 klen klen  27209910 Aug 10 15:32 libboringssl.a
-rw-rw-r-- 1 klen klen   1213616 Aug 10 15:32 libgpr.a
-rw-rw-r-- 1 klen klen 172648038 Aug 10 15:32 libgrpc.a
-rw-rw-r-- 1 klen klen  52885946 Aug 10 15:32 libgrpc  .a
-rw-rw-r-- 1 klen klen  10001966 Aug 10 15:32 libgrpc_abseil.a
-rw-rw-r-- 1 klen klen  28759698 Aug 10 15:32 libgrpc  _alts.a
-rw-rw-r-- 1 klen klen    127288 Aug 10 15:32 libgrpc_csharp_ext.a

git version is 1.8.3.1, My question is why can not git clone the libraries fully?

CodePudding user response：

Check if this is linked to the http.postBuffer when those librairies were added and pushed.

But ideally, you would not add them to a Git repository in the first place.
Those kind of deliverables belongs to an artifact referential, like Nexus or Artifactory.
That way, you can add to your project a config file declaring your dependencies (like a pom.xml), instead of asking a source control system like Git to restore huge files.

The other approach would be to use Git-LFS, but it might not be fully supported by an old Git 1.8.x from a RHEL 7.x or 8.X.

CodePudding user response：

As @fredrik said, After install git-lfs, I can download the libraries fully.

curl -s https://packagecloud.io/install/repositories/github/git-lfs/script.rpm.sh | sudo bash

sudo yum update

sudo yum install git-lfs

I am not sure if this installation method works for everyone, see this
